"A new Rasmussen Reports national telephone survey of Likely U.S. Voters shows Obama picking up 46% of the vote, while Perry earns support from 39%. Fifteen percent (15%) are either undecided or prefer another candidate. Two weeks ago, Perry was up by three. Three weeks ago, the president held a three-point edge over the governor.

IF I WERE THE REPUBS I WOULD SAY NO MORE DEBATES 
Of course, you forget that 80% of undecideds go for the challenger vs. an incumbent. So, that would, in an actual election, read closer to Perry 51%, Obama 49%.
Plus, look that the demographics of voters. Obama's bleeding whites, independents, and as of late Jewish voters. He's under 50% with Latinos. But, for myopic black voters (most of whom are concentrated in portions of the country that go blue anyway), he'd be near the 20s by now.
