Herman Cain is polling just 2 points below Rick Perry.

A statistical tie, in this FoxNews poll. Cain has jumped from 6% in last FoxNews poll to 17%. FoxNews declares that he's now in "the top tier." Wow.

And Mitt Romney is leading, though all three of them are technically in a statistical tie: Romney 23%, Perry 19%, Cain 17%, with a 5% margin of error. (Full poll results.)

The poll might be misleading, since it was taken right after the glowing media coverage of Cain for winning the Florida straw poll. But if you're Rick Perry, you have to be worried that even one outlier poll is showing you neck and neck with Cain.
