With Herman Cain rocketing in the polls, could the Cain-Romney bromance officially end tonight?

The numerical logic is strong. But I actually wonder if Mitt’s going to go down that path. In some ways, Cain could be useful to Romney. I don’t think anyone thinks Herman Cain is going to be the Republican nominee. So he’s a much more convenient person for the right-wing of the party to get all jazzed up about than Rick Perry, who definitely could be the nominee.

Curious what you think.
