Today Herman Cain hold's a small lead over Obama in a hypothetical contest between the two. He's the only Republican candidate to be in that position today, although Romney had a lead over Obama previously.
I know it's early and means little right now, but it does show that the "Cain Train" is making itself known and enough people are paying attention to his message.
And "they" said it couldn't be done.
