President Obama is building his lead in Florida, Ohio and Virginia over Republican presidential nominee Mitt Romney, according to polls released Thursday.

A series of NBC/Wall Street Journal/Marist College polls released Thursday evening show Mr. Obama with identical leads of 49 percent to 44 percent in Florida and Virginia and 50-43 lead in Ohio, as he appears to be enjoying a bump in support following last week’s Democratic National Convention.


The polls were conducted from last Sunday to Tuesday.

The Romney campaign has dismissed recent polls in the president’s favor as the temporary result of a post-convention “sugar high,” but the numbers could be a troubling sign for Mr. Romney, whom many analysts say is fighting an uphill battle and will have to win a majority of swing states including Florida and Ohio if he hopes to win the presidency.
