A new Wapo/ABC poll shows that 59% of the voters think President Obama will be reelected vs. 34% who think Mitt Romney will win. Note that this is a completely different question than who the voter supports. The polling data on who people will vote for gave Obama a mere 3% lead, 49% to 46%. In other words, there are millions of voters who want Romney to win but don't expect him to do so.
Another take on this is to look at the betting site intrade.com where bettors are giving Obama a 67% chance and Romney a 33% chance. That is 2 to 1. Romney's problem is that he has tanked in the past week, presumably due to the furor around his criticism of President Obama, before he knew all the facts concerning the riots in Egypt and Libya, where four American diplomats were killed. Here is a chart of Romney's chances for the past 30 days.
