On the eve of the one and only vice presidential debate 2012, more polls are bringing more good news to Republican presidential nominee Mitt Romney (especially where it counts; in the battleground states).

A new Wall Street Journal/NBC News/Marist College survey founds Mitt Romney and President Obama in a dead heat among likely voters in Florida, with Obama at 48% versus Romney’s 47%. The situation is similar in Virginia, where Romney holds a one-point lead over Obama (48% to 47%). However, in the crucial battleground state of Ohio, Obama is retaining a 6-point lead over Mitt Romney, 51% to 45%. No Republican has won the presidency without winning Ohio.    

Similarly, a new poll by The New York Times/CBS News/Quinnipiac University is registering gains for the Republican ticket in swing states. In Colorado, the race is in a statistical dead heat with Romney up one point over Obama (48% to 47%). In Wisconsin, home of Republican vice presidential nominee Paul Ryan, Obama is still in the lead over Romney, 50% to 47%. 

Though tonight's debate is not expected to move the needle one way or another, Democrats are expecting Vice President Biden to deliver a solid performance in order to undercut some of the momentum Mitt Romney has gained from his win over Obama in last weeks' first presidential debate. Conversely, Republicans hope a Ryan follow up to Romney's strong performance in Denver can continue chipping away at President Obama's narrowing lead in the coming weeks. Either way, it will be a horse race all the way to November 6.
