A new poll has President Obama, a Democrat, pulling ahead of Republican candidate Mitt Romney in Virginia, a crucial swing state. The Quinnipiac University poll released today finds Romney, the former Massachusetts governor, would get 43 percent of the vote compared to 47 percent for Obama. In three previous Quinnipiac polls in Virginia, in September, October, and December, Romney edged out Obama in a head-to-head match-up. The poll shows women and independents are now backing the president over Romney.
