Clue yet to Election Night . Who do you think is going to win . And good evening tonight from cleveland, ohio. And were here tonight because both campaigns are counting on ohio and its 18 electoral votes on Election Night. The president needs ohio to hold onto his midwestern firewall. Romney needs ohio because without it, the math for him is very difficult. Which is why we discovered a frenetic pace, as we were allowed inside both campaigns, working on the ground here today to get out the vote. Governor romney in cleveland. Tonight, his Campaign Says his ground game is well ahead of john mccains four years ago. President obama rallying his supporters in cincinnati tonight. Polls here in ohio showing a slim lead for the president. And tonight, the newest abc News Washington post poll and it shows why getting out the vote across this country, and right here in ohio, will make all the difference tuesday. President obama ahead by just one point tonight. And look at the map. Heading into the weekend, governor romney making 14 stops, seven battleground states, the president , 14 stops, eight states. And nowhere have they been more than ohio. Tonight, our countdown clock is on and so is our Powerhouse Political Team. With two days to go, our whole team here tonight. Were going to begin tonight with our senior White House Correspondent jake tapper in cincinnati. Reporter as the candidates crisscross battleground states, its as if theyre on different planets. Both campaigns claim victory is within reach. Their pitches combinations of soaring rhetoric and needy cries to not buy what the others are selling. Hes hoping well settle. Americans dont settle. We build, we aspire. We dream. We can do better. Their bet is on your cynicism. But florida, my bet is on you and your hope. Reporter to appeal to undecided voters, sick of d. C. Dysfunction, both candidates are cloaking themselves in bipartisan robes. Ill endeavor to find those good men and women on both sides of the aisle who care more about the country than they do about politics. I want all parties to work together. And were not democrats and republicans first, were americans first. Reporter and as a sign of just how close the Obama Campaign thinks this could be, the president today appeared in new hampshire, which has only four electoral votes. He was joined by bill clinton, who mocked romneys pitch. Dont pay too much attention to what our solutions are, just be disappointed in it. Look at me, i look like a president. And i talk like one. And im telling you its all going to be all right if you elect me. Reporter the president wistfully told his supporters the campaign is no longer about him or his team. Were no longer relevant now. Were props. Because whats happened is, now, the Campaign Falls on these 25yearold kids who are out there knocking on doors, making phone calls. Reporter romney appeared in pennsylvania this evening. Its unclear if going to the state that hasnt gone republican in a president ial race for almost a quarter century was a bold sign of confidence that hes getting ahead of a romney wave, david, or a desperate attempt to find a path to the presidency that does not include this state that you and i are both in, ohio. David . Jake tapper here in ohio with me tonight. Jake and i have been crisscrossing each other, covering both of these campaigns. And with the race this close tonight, it will all come down to which campaign can get the vote out. In one cleveland suburb today, we discovered that dueling campaigns can actually watch one another from across the street. Were here at the obamabiden field office in one of the suburbs surrounding cleveland, and just to give you an idea of how crucial these votes are in the suburbs, how competitive both campaigns are for these votes, i wanted to show you how long it would take us to get from the obama field office to the romney field office. We literally drove down the parking lot and, well, look across the street. Theres romneyryan. How are you . Good to see you. Reporter few days left. And thats where we started, with the team trying to unseat the president. And they know they need ohio. Inside, you can sense it. They know they have just few precious hours left. So, this is the buzz, two days out. May i please speak with michael . Reporter volunteers calling lists of voters who they believe lean republican. So, the people you are calling right now, you have a hint they could be leaning republican, you just need to get in touch with them. Thats exactly right. Reporter president obama won this county four years ago. George w. Bush won it in 2004 and they are determined to flip it back. Tom gave up his sunday with his family to knock on doors. Are you missing a game to do this . Well, you know, i have a radio in the car, so reporter youll have the score. That score tuesday night more important to him. Well, i think were at a very critical point, a historic election. Reporter we ride with him in a small team of volunteers to find the undecided voters. The Romney Campaign telling us they believe thats a pool of just 2 of ohio voters, perhaps even less. They find one. I havent made up my mind yet. Reporter russ, a dad, an electrician. How many times have you been called or contacted . Quite a few times. Reporter tonight, he says hes leaning obama, telling me help for the middle class is most important to him. But the romney team not giving up. This is a gentleman who says hes been contacted several times by both you guys and the obama team. Look, i mean, were not taking absolutely anything for granted. Reporter nor is the team inside that obama field office, back across the street. How are you doing . In one of the back rooms, you dont hear phones ringing. Instead, you hear the printer. Printing up stacks of maps. They call it cutting the turf. And this one turf alone, how many houses . This is 15 or 20. Reporter and every one of them, a voter who they believe if they meet them face to face, will vote for the president. Every dot on this map is going to be someone who gets a knock today. Yep. And tomorrow and tuesday. Reporter theyre going to love you in that neighborhood. David, a grandfather, says hes knocking on doors for his grandchildrens future. And he finds this woman, he asks her if hell vote early but she says she wants to stand in line on election day. Thats just you like that experience . Yes. Yeah. You saw that volunteer there, find another voter. You also heard him ask her to vote early. Both campaigns urging supporters to vote before tuesday and the lines have been extraordinary across this country. More than 27 million americans have cast their votes in 34 states and the District Of Columbia already. The wait so long in florida, tonight, the fight to keep some of that early voting open longer. Abcs cecilia vega is watching the lines in tampa tonight. Reporter chaos in miami. So many voters showed up today, overwhelmed poll workers briefly locked polling place doors. All weekend long, the lines to vote early went on and on. For some, the wait was six hours. This is ridiculous. Reporter new changes to floridas voting law cut down early voting by one day. Making saturday the last day to cast an early ballot. The republican governor refused an extension and, in the middle of the night, democrats filed an emergency lawsuit. A judge ordered one polling place near orlando to stay open sunday after it shut down early because of a bomb threat. And polling places in a handful of other counties where the lines were especially long opened sunday so voters could cast absentee ballots in person. And this is one of those polling places outside of st. Petersburg where you can still cast an early ballot. President obama won narrowly here in florida four years ago. So far, democrats have outpaced republicans in turning those early ballots in. David, both sides now waging a fierce battle in these final few hours. A battle already, cecilia vega in florida, where shell be on Election Night. Cecilia, thank you. Every four years, we watch as the vote comes in and whoever wins the electoral map, the electoral college, wins the presidency. You need 270 electoral votes to win. And so tonight, gma anchor and this week host George Stephanopoulos with the bottom line on the best path for both campaigns. George . Reporter in these final hours, david, scheduling is strategy, and for president obama, its all about his midwest firewall iowa, wisconsin and that big prize, ohio. Hes hit those states every day since friday. They are going to be his last three stops on monday. And this electoral map shows why. If president obama can win these three on top of the solid blue states democrats have taken in the last several elections, hell have the 271 electoral votes he needs to win, even if governor romney sweeps all the rest of the battleground states. Which is why you do see governor romney making a late play for pennsylvania. Hes going to be there today, in the suburbs of philadelphia. Pennsylvanias 20 electoral votes are an insurance policy against a loss in ohio. Democrats are calling it a hail mary, but the race is tighter than expected there, so, the gamble makes some sense. Romney will need to win pennsylvania if the president s firewall holds. David . George stephanopoulos, who will be guiding us all through Election Night, thank you. And now to a key group both sides have tried to court, the hispanic vote. Our latest poll shows the president leads among hispanics, 66 to 28 and keep in mind, john mccain got 31 , more than that, four years ago. How big a role will hispanic voters play . We turn to our partners at univision and jorge ramos tonight. Jorge . Reporter david, the new rule in american politics is that no one can make it to the whitehouse without the hispanic vote. This tuesday about 12 million latinos will go to the polls but it will be very important to watch what hispanics do in crucial states like colorado, nevada and florida. It is no surprise that those states are being bombarded by political ads en espanol. Historically, latinos tend to vote more for democrats than republicans and that wont change, presuming president barack obama will get the majority of the hispanic vote 3 to 1. But if mitt romney can get more than a third of the latino vote, it will be a very, very close election. The most important issues for latinos are jobs, education and health care, but immigration defines who is with us and who is against us. Immigration is personal. President barack obama wants to legalize millions of undocumented immigrants. Mitt romney says he doesnt want an amnesty even though he talks about a permanent solution. Jobs might not be as important for latinos as immigration. Well see that on tuesday, david. Jorge ramos, thank you. On tuesday night here, diane sawyer, George Stephanopoulos and our times square election headquarters. Jake tapper with the president , ill be with mitt romney. The entire Powerhouse Political Team out for what could be a very long night. Well see you tuesday night here. But from forecasting the president ial race to the weather now, and to an unwelcome system tonight. For the millions who survived Hurricane Sandy and so many still without power, now, a new storm is brewing and bringing bitter cold. So Many Americans whose homes are shattered are now being exposed to plunging temperatures. So, abc meteorologist ginger zee back at the map in new york tonight to talk us through this. Ginger . Reporter good evening, david. Hypothermia is the main concern. Here is why. Temperatures are dipping tonight around philadelphia at 34, atlantic city, a very hardhit shoreline there at 30, new york city and just outside of it, right at or even some places below the freezing mark. So, its a number that i need to show you and i cant tell you that theyre going anywhere. The 30s going to stick around all the way through most of the week. So, its not like this is lifting. And then, ive got another threat, of course i do. Youve got that low pressure system that becomes that noreaster, that kicks back rain, wind. Were talking one to three inches of rain. A very vulnerable shoreline there, going to get 6 to 12foot there at the jersey shore and elsewhere, going to get 6 to 12foot waves and then you add more mix of cold, poconos get a little bit of snow. David . Couldnt come at a worst time. Ginger, i know youll be tracking this the whole way through. Thank you, ginger. And weve been tracking the hunt for fuel since sandy hit. With more than a million and a half still without power and gas stations running dry, there is a ray of hope tonight. And abcs alex perez is in new jersey this evening. Alex . Reporter well, david, this is the sight so many people have been desperately waiting to see. Take a look at that. Tankers full of gas, ready to help. Finally, some relief. This is one of ten fema gas Distribution Sites across new york and new jersey. This one is dedicated to helping first responders. But there are sites where residents can also go fill up. A tengallon minimum. But at locations not near these sites, you will see still many long, long lines of cars and people with containers. The feds have cleared the way for some 22 million gallons of gas to be made available to stations that have run dry. These ten fema locations have about 200,000 gallons of gas that they will be distributing, but it will still be some time, the gas situation, not expected to return to normal until about late this week. David . Alex perez has been on this every step of the way. Alex, thank you. And we want to tell our viewers at home here, our Parent Company disney is organizing a day of giving on all of our programs, beginning with Good Morning America and all the way through world news and nightline. Well be reporting on how we can all help the victims of the storm. Thats tomorrow, all day long, right here on abc. In the meantime, we turn now to a tragic incident at a zoo in pittsburgh. A small child falling into a pit with wild animals. The description of the attack is difficult. Heres abcs mark greenblatt. Reporter african painted dogs like these are similar to wolves, naturally hunting in packs, which is how they attacked a 3yearold boy today who fell into their exhibit at the pittsburgh zoo. The zoo says the boy was with his mother when he fell 14 feet over a railing and off a mesh barrier where the painted dogs were. A zookeeper snapped into action, immediately getting seven of the 11 dogs out of the exhibit and into a building, while another employee shot darts at the other four, trying to scare them away. But it all wasnt enough. It is with Great Sadness and very, very heavy hearts that we report today that a small child was killed by our african painted dog pack.
