High anxiety in cleveland and chicago, history on the line whos it going to be . Nightly news begins right now. Announcer from nbc news World Headquarters in new york, this is nbc nightly news with lester holt. Good evening, the polls are close and the battleground map is shifting tonight. But Hillary Clinton seems to be holding the inside track. Leads in key battleground states offering her multiple pathways to victory next donald trump is advising his own victory lane through florida, tonight both campaigns are on the attack and focusing on an evershrinking map. Well take a close look at the map on the state of the race with chuck todd in a moment. Lets begin with las vegas with nbcs kristen welker. Tonight the clinton team is getting some good news, new polls showing her with leads in the key states of wisconsin and pennsylvania. But donald trump has nevada. With just six days until election day, clinton is harpening her attacks. With polls tight in florida, Hillary Clinton adding a surprise stop today, an escalating her scorched earth strategy against donald trump. Last night showing a rare flash of anger at a protest rally. I am sick and tired of the negative, dark, divisive dangerous vision and behavior of people who support donald trump. Clinton reviving old attacks, looking to phe by the time you add up all the people hes insulted, thats more than half the population of the united states. And letting her surrogates take on the email controversy, president obama speaking out for the first time, seeming to take a swipe at the fbi directors timing. There is a norm that you know when there are investigations, we dont operate on innuendo, we dont operate an incomplete information. We dont operate on abedin at the center of the fbi probe in new york today. Scheduled to return to the campaign tomorrow. But today, clinton sending out six top surrogates, including the president with james taylor in north carolina. Now we got to focus on some business. The president trying to energize his 2012 base, including africanamericans. Our latest nbc News Analysis showing early voting among africanamericans is lower than where it was at this point in 2012 in florida and north carolina. As clinton tonight is vote. Did you vote for Hillary Clinton or against donald trump . Against donald trump. Latino support critical if clinton is to win battleground nevada. They may get above 20 , a fifth of the electorate, theyre energized to vote against donald trump. Clinton counting on the Obama Coalition more than ever to get her across the finish line. Kristen welker, nbc news, las vegas. This Peter Alexander in the florida panhandle. In front of a sea of take his late surge for granted. Well pretend were down. Now we got to win, we got to win big. The republican nominee prone to adlibbing in these final days, sticking to the script. She is the candidate of yesterday. We are the movement of the future. But trumps political future relies heavily on florida. Now a razorthin race. Lose here and Hillary Clinton is virtually a lock for the white house. Why trump is making his 16th visit in in pensacola, trumps ground game is uncharacteristically visible. Less than a week until the election, 5,000 calls made today. But its a duel with democrats. Trumps latest message urging his backers to vote early and hers, to reconsider. This is a message for any democratic voter, who have already cast their ballots for Hillary Clinton. Remorse. At least seven states allow voters to change their earlier absentee ballots with restrictions. Trump today again attacking the media as dishonest. Even targeting nbcs katie tur. Theyre not reporting it, katie. Youre not reporting it, katie. Theres something happening, katie. The Fiery Campaign rhetoric is now spilling over. In mississippi, a 111yearold black church burned overnight. What police call a hate crime. Vote trump sprain quote that was placed on the church is basically an intimidation of someones right to vote. Whatever way they choose to vote. Tonight the Trump Campaign is condemning that chump burning. Here in florida to give you a sense of how close the race is, we did the math. More than four million early and absentee ballots have already been cast and just 9,000 votes separate registered republicans from democrats. Left centre. Peter, a lot of math being crunched. The map. Our brand new battleground map with six days to go. Chuck todds at the wall. Chuck, what has changed . The math and the map. This is the current nbc news battleground state projection as you can see, its gotten more competitive. But Hillary Clinton is still over 270. Some of the moves we made, north carolina, went out of her column and into tossup. But as you can see, while things have gotten better for trump, he still cant, he can win all the battleground states, sweep out west, florida, north carolina, ohio and he short because hes got to break through what weve been calling the big blue wall, pennsylvania, michigan and wisconsin. Today he didnt get good news, a new poll out in pennsylvania, 5point lead for her, quinnipiac poll holding steady. Trump stuck at 43 . In wisconsin, when i did this last night, i indicated its possible wisconsin could be the pivot state. Well the Gold Standard of polling there is marquette university. Came out today, identical to the size of lead and victory margin for barack obama in 2012. Bottom line if they dont break through this big blue wall, he doesnt have a path to 270. Nicole wallace, nbc news, a veteran of president ial political campaigns. Six days to go. Are you sitting there with the map and the numbers . They are and certainly in the case of the Trump Campaign, which admitted they havent built the kind of infrastructure that normal campaig a lot of their information from newscasts like this. Heres the cold, hard truth for them. The bestcase scenario, if they do everything right, they lose with 266 electoral votes, if you know that the wind is not at your back, structurally the race is almost out of your reach, they got their break friday and everything weve seen so far looks like it might not have been enough. If youre the clinton campaign, you dont want to make any obama was out. All of her super surrogates will be out in force. To the power struggle. Up and down the ballot, beyond the president ial race, there is a big fight for the senate under way. The question of which party has control hanging in the balance. The impact is going to have farreaching effects, starting with the next president S Supreme Court pick. There are many races that are currently polling within the margin of error. Nbcs Halle Jackson has more. For months, its and clinton. But these are the names that could really change government. By either helping republicans keep control of the senate, or propelling democrats to a majority. The power to promote the next president s policies or push back. The gop is looking for star turns from names like marco rubio in florida. We have a tough fight of our own. The congressman joe heck is in his own fight in nevada. A race that reflects whats happening all my opponent continues to support somebody who has been deemed untrustworthy by the majority of americans. Thats the argument that roy blount is making in missouri. Im jason candor, and senator blount has been attacking me on guns. In north carolina, senator richard burr had to apologize after seeming to joke Hillary Clinton should be shot. Its got a picture of Hillary Clinton on a little bit shocked at that. It didnt have a bullss eye on it. If those candidates pull out wins, republicans will probably keep controlling of the senate but if democrats come out on top, it will be a rise to power fuelled in part by women. Like Maggie Hassan in new hampshire. Katie mcguinty leading in pennsylvania and Tammy Duckworth in illinois. All but assured a victory after this debate moment. I had forgotten george washington. Senator mark kirk forced to say hes sorry for seeming racist. What republicans are hoping for, that enough voters will split their tickets to help republican candidates. And underscoring how much is at stake here, more than 344 Million Dollars has been pumped into just the top five most Expensive Senate races. An extraordinary amount of money. Left centre. Halle, thanks. To the deadly ambush in the early iowa. Police officers targeted, shot and killed while sitting in their squad cars that triggered an allnight manhunt. Authorities tracking down a killer. A suspect who is in custody and a Youtube Video may hold some clues to a possible motive. We get the latest from nbcs blake mccoy in des moines. With guns drawn, officers canvassed the iowa neighborhood where two of their own had just been ambushed. Fearing they could become the next 1 06 a. M. , Police Responding to a call of shots fired found urbandale officer Justin Martin shot dead in the front seat of his squad car. A rookie officer, this was his first year on the job. 20 minutes later, two miles away, des Moines Sergeant tony beminio was found shot in his squad car. A husband and father. He died at the hospital. They were seated in their car, they didnt have a chance to defend themselves. Identify 46yearold scott miken greene as their suspect. He turned himself in hours later. Greene is well known to police in the area, posting a recent runin with officers on youtube after being asked to leave a High School Football game for holding a confederate flag. You grabbed me. Ill escort you outside the stadium. Greene lives here with his mother, who neighbors say was trying to evict him. We never would have guessed that it would come to this. That he was that unsettled. Nationwide, 115 officers have been killed in the line of duty. A fiveyear high. 16 in ambushstyle attacks like the ones today. And earlier this year in dallas and baton rouge. For those who knew these officers, heartache. The men were just doing their job, it was senseless. A Law Enforcement source tells us the suspect has a history of mental problems, but investigators are trying to determine what set him off this are pouring in. President obama, Hillary Clinton and donald trump among those offering words of support. Left centre. Blake mccoy, thank you. Still ahead, the outrage over insulin. Why costs for the lifesaving drug used by millions, including many children, has soared 400 in recent years and how patients can fight back. Were in chicago and cleveland for the two most .

Nbcs jolyn kent went look for answers on why and what parents can do. Now she and her dad are the kara family alive. His type i diabetes demands at least a dozen shots of insulin daily and the cost has doubled in the last five years. How does that make you feel . It makes me feel like im paying somebody for my kids life. The karas now spend about 1800 a year after insurance, on insulin and supplies. Thats half a car payment of a brand new car. Insulin have shot up as much as 400 in the past ten years. Desperate patients are pleading online saying they cant afford the insulin they need to live. Prices are set by the pharmaceutical companies and whatever the market will bear. Increases in prices over the last few years is because you know companies are recognizing an opportunity to raise prices. Drug makers blame Insurance Companies saying more patients have high deductible plans, meaning they must pay more for cards are available, but patients dont always qualify for them. Im paying attention and i guarantee you every single mom out there is. We all know whats happening. All three insulin makers tell nbc news theyre working to make insulin more affordable. Sanafi says it has not increased the price in almost two years. Consumer reports recommendes if you dont have insurance, check prices at walmart and costco. Contact patient assistance programs like tif tiffany found a card on the drugmakers site. I have to sell my house, sell my cars, were going to keep our kid alive.
