Romney has two main things going for him. He leads the President 45-36 with independents. And he's also benefiting from a much more unified party with 88% of Republicans committed to voting for him while only 83% of Democrats say they'll vote for Obama.
Our national survey confirms the wide electability gap between Romney and the rest of the Republican candidate field. Obama leads both Newt Gingrich (49-44) and Ron Paul (46-41) by 5 points, Michele Bachmann (50-41) by 9, and Rick Perry (50-40) by 10. It continues to look like if GOP voters really want to defeat Obama they pretty much have to nominate Romney.
