Obama Pulls Ahead Obama gains momentum in swing states, makes tough road for Romney By Mark Russell, Newser Staff Posted Sep 9, 2012 7:37 AM CDT 122 comments Comments President Barack Obama addresses the crowd at a rally at St. Petersburg College's Seminole Campus yesterday in St Petersburg, Fla. (AP Photo/The Tampa Bay Times, Will Vragovic, Pool) (Newser) – President Obama's DNC acceptance speech may have inspired more yawns than fervor, but the latest polls are showing him a clear advantage, especially in several key swing states, reports Politico. Republican officials admit that their in-house tracking polls show Obama with a high-single-digits lead in crucial battleground state Ohio. While Mitt Romney can win the presidency without Ohio, it would be very tough. “Their map has many more routes to victory,” said a leading Republican official. The biggest worry for Democrats at this point is that the 6% to 8% of voters who are still undecided are overwhelmingly white, middle-aged, and economically stressed—bad demographics for Obama. But with polls showing a small but clear bounce for Obama, the president is now a "reasonably clear favorite," writes Nate Silver at the New York Times. Obama is now leading by four percentage points in Gallup's national tracking poll, two in Rasmussen's, four in Ipsos', and three in RAND's polling. Campaign officials say they don't expect many big changes over the next couple of weeks, as attention turns to Oct. 3 and the first presidential debate.
