Poll: Hillary Clinton, Newt Gingrich Negative Ratings Lead Presidential Candidates

Obama has fared the worse over the past few months with the biggest decline since August. His core opposition percentage has grown from 35% then to 43% today. Over the same time period, his core support percentage fell from 29% to 25%, which give him a -18.

Based on these results, it is going to be the voters who are leaning one way or the other who are going to make the difference, those who say they are very likely or somewhat likely to vote for a particular candidate. And the voters who have not given any opinion will play a big roll also.
