This was once a TNR staple, and every now and again, it rears its strange head. To wit, from yesterday's WaPo:

And today from Reuters:
According to a Reuters/Ipsos poll on Wednesday, President Obama leads all potential Republican challengers by double-digit margins. He is ahead of his closest Republican rival, former Massachusetts governor Mitt Romney, by 13 percentage points – 51 percent to 38 percent.
The key thing, I guess, is to take any single one of them with total skepticism. Especially at this stage of the game. But a gap of 13 points is pretty staggering. Especially when the samples are pretty much the same size.
