Thank you. Woodruff from president obama today, a new call for caution in the response to ebola. He urged states not to enforce policies that suggest the u. S. Is shying away from the fight. The warning came as another dallas nurse was declared free of the deadly disease. Woodruff amber vinson was all smiles at atlantas Emory University hospital this morning. As a nurse, and now as someone who has experienced what its like to be cared for through a lifethreatening illness, i am so appreciative and grateful for your exceptional skill, warmth and care. Woodruff the 29yearold vinson is the second of two dallas nurses to be cured of ebola. They caught the virus from thomas eric duncan, a liberian man who died at a texas hospital. Dr. Bruce ribner oversaw vinsons care at emory, but he concedes, there are still Unanswered Questions. We are not aware of the specific details of what occurred in the dallas facility or how transmission occurred in that environment. Woodruff equally unclear, just how vinson recovered so quickly. To that, the doctor said the honest answer is, were not exactly sure. Another nurse, kaci hickox, was back in maine today after being held in an isolation tent at a newark, new jersey hospital. She treated ebola patients in sierra leone, but has shown no symptoms herself. Authorities in maine said shell remain quarantined at home, but her attorney insisted no such arrangement is in place. Leading Health Officials have warned that quarantines may deter doctors and nurses from going to west africa to help. America cannot look like it is shying away because other people are watching what we do. Woodruff at the white house today, president obama said the medical volunteers should be applauded and supported, but he also defended the decision to quarantine u. S. Soldiers who serve in the ebola zone. The military is in a different situation obviously because they are first of all not treating patients. Second of all, they are not there voluntarily. Its part of their mission thats been assigned to them by their commanders and ultimately by me, the commander in chief. So we dont expect to have similar rules for our military as we do for civilians. Woodruff in addition, the pentagon said the joint chiefs are recommending that all Service Branches quarantine their troops who serve in west africa. Overall, the World Health Organization estimates 10,000 people have been infected there, but the head of the u. N. Ebola mission warned today the true number could be far higher. Anthony banbury told the Associated Press in the face of that uncertainty, the president of liberia, Ellen Johnson sirleaf, appealed anew for outside help. She said the world must recognize that ebola poses a global threat. Woodruff president obama plans to meet tomorrow with Public Health workers whove been to west africa, or plan to go.

Woodruff still to come on the newshour North Carolinas closely fought senate race; the influence of Third Party Candidates on the midterm elections; iraqs displaced search for safe refuge; how ebola is affecting business and trade worldwide; tracking americans mail delivered by the u. S. Postal service; a thriller details the heist of a lifetime, breaking into the Federal Reserve bank. Ifill early voting has already begun in key states that could determine the balance of the senate, and the direction the nation may be heading in the final two years of the obama presidency. One of those states is North Carolina, where a democratic senator is defending her seat in a state the latest polls show could go either way. For most North Carolina voters, this is what next weeks Senate Election as boiled down to. Kay hagan enabled president obamas worst ideas she refuses to clean up his mess. Shes a hypocrite covering up from missing critical votes. Senator kay hagan says she puts views first. We votes with bam obama. Running an ad that lot our soldiers die in vein. 90,000 ads. Up to 100 million spent. Slashing messages from democrat kay hagan. North carolina is not for sale. How are you doing . Ifill from challenger thom tillis the republican speaker of the North Carolina house. We need independentlier ship that will stand up to your own party when you disagree. Were going to win. Ifill the political poll has prepared hagan who was first selected the year president obama won North Carolina and tillis who came to power in 2010 after republicans took over the state house for the First Time Since reconstruction in to a genuine final week dead heat. At Duke Stanford school of public policy. Turn out is going to be key for hagan for her in order to win. Theres not going to be a turn out like there was among minority voters and Younger Voters for obama. But shes got to get some of that vote. This is not 2008. Not even 2012 this is a smaller, white are, older, richer, electorate but shes got to get some of that vote out. Ifill at this weekends state fair, the voters we talked to had already made up their minds. She is for tillis. As in all campaigns theres a lot of mud slinging going on, unfortunately. Which doesnt interest me. I want to know what the candidate is going to do, what theyre not going to do, their believes, what they stand on. Ifill andy jones and his friends are sticking with the democrats. I like kay hagan, i like that she has experience. I think that the amount of money that is poured in to this race with Television Ads is kind of silly. Its become a very hateful, just throwing mud at each other and seeing what sticks, i think thats silly. Ifill its taken a lot of talk and money for this campaign to go down to simple choice between democrat who would rather talk about education and equal pay and republicans who is anxious to link his opponent toe National Issues like ebola and isis. The recurring disagreement was on display as we sat down with both candidates this weekend. Has put forward the most disastrous legislative record weve seen in North Carolina. He is taking our state backwards, what did he he gave tax cuts to the wealthy and balanced the budget on the back of everybody else. The middle class, hes rigged the system against Small Business but he has gutted public education. I this this f its the truth about education we have given 7 raise largest raise in a generation. So if all senator hagan has are statewide issues, nothing to point to at the National Level that shes proud of, other than rubber stamping president obama 96 of the time, i think shes in trouble with the citizens of North Carolina. How are you doing. Ifill tillis mention mr. Obama by name in virtually every sense. Never missing the opportunity to link an unpopular president to the states incumbent president. Senator hagan, president obamas policy, he said ifill does the president hurt your campaign . You know, this election is about the people of North Carolina. And with the president , i support increasing the minimum wage. I supported his very first bill, my very first bill, the fair pay act. But also opposed the president on things that werent good for North Carolina. Ifill replacing president obama on the stomp in tight races like this one, hillary clinton. Elections come down often to whos got more money. Whos pedaling more fear. And who turns out. And there is nothing more important for kay than who turns out. Ifill tillis has attracted National Support including this visit from g. O. P. Chairman. I know that if we work really hard together that we can get thom over the finish line, not for the party, not for the majority, for power. To do this to help save this country. Ifill both candidates are getting a tremendous boost from outside groups on the right and the left. From the coch brothers to planned parenthood kicked in more of 70 million. North carolina very well made determine the future of the United States senate. This race between kay hagan and thom tillis has been focus for months for us, it is the most important race in the country. Ifill to add to the uncertainty third candidate, libertarian sean haugh could tip the balance even if he gets a small percentage of the vote. The dynamic, i dont want to vote for the incumbent so im looking around who i vote for to the extent you vote for a third party you dont vote for the challenger. Ifill thousand of north carolinians descended on lexington for the barbecue vest call. Spending has gotten so out of control at least that im one that thinks that states should have more control of the money that they have instead of sending to washington having to do stuff to get it back. Ifill and william is one of the thousands of volunteers working the state for hagan. The wife and i we found that, thank the lord, showed up, were here, glad to see you. Ifill but the money, the finger pointing, the positives tile Television Advertising leaves many voters perplexed. Some view it as a sport, its my team versus your team, whoever has the money has better ground game. You need money for print. The same thing, its about mitigate and Birth Control and College Funds and like one is for the rich one is for the poor. Ifill this last wild card, new voter i. D. Laws that republicans call protection and democrats call suppression, but if thats true in state that both National Parties now see as their key to the south. Woodruff in North Carolina, the libertarian on the ballot could help tip the result. Across the country, in at least ten races, both parties are wondering what effect independent and thirdparty candidates will have. Where do they have a chance at winning and where are they just spoilers . And what does it say about our politics when so many of these candidates are getting significant support in the polls even without campaigning . Here to help answer some of those questions is Jonathan Martin of the New York Times, whos been reporting on many of these candidates. Thanks. Woodruff which states are we looking at are you looking at when it comes to third party or independent candidates. Most important one is kansas where youve got greg orman an independent running against pat roberts who is republican. This race is very competitive and crucial, i think the most crucial race involving Third Party Candidate because if democrats do lose would give the majority. But senator roberts, could be in the hands of greg orman, never served in office who could decide the fate of the senate. He has not said which party hes caucusing with. He will not support Mitch Mcconnell or harry reid the two senate leaders. If we have a result next tuesday where this comes down to one state where a Third Party Candidate could very crucial candidates. Woodruff so can scan is one. There are some other states where you have libertarians, North Carolina where gwen was. Very important. The others are more spoilers i would say. North carolina comes to mind when you have a libertarian who looks to take about 5 right now in the polls that could be really important in a close race. And especially depending where those votes come from, are they coming from the cob servetive side or more liberal side. The florida florida governors race. Dont want either candidate quite frankly. Is this a protest vote, a third party to stay a pox on both your houses. Last one is the maine governors race where you have pretty significant Third Party Candidate running there who is taking votes mostly from a democrats who i think otherwise would be in command of this race. Woodruff its not in every case, its not one party that is suffering from these. Thats exactly right. Woodruff it varies. It sure does. Woodruff tell us why you i saw story you wrote unusually large number ever these candidates this year. Why is that . Well, i think people are so fed up with washington, with politics right now that they want to go out on their own, some of them are ideological passions, others are doing it because they truly are unhappy with the two party system. Now, its politics, there is also opportunism. A better path to be viable if youre not tagged with either party label. Woodruff talk about how the major parties are dealing with, rand paul who is beloved by libertarians, has been in kansas, which we were just talking about. Appealing, saying hes voting for pot roberts hes a republican. What are the republicans doing and what are the democrats doing . The republicans are water down some of these libertarian candidates who they feel would take votes from republican candidates in the state. Theyre doing that by deploying people like rand paul who have a following of libertarians, with both Retail Campaign event in the state. Also airing tv ads for the rand paul tries to appeal to libertarians. And maine republicans have an ad that touts Third Party Candidate because they know better he does, the more votes takes from the democrat. Its going on. The democrats, its a little bit different i think right now theyre trying to be careful in kansas because while they that i mr. Orman being independent would caucus with them, they dont want to come out too hard for him because that would sort of make him more d
