Again, it's all about electoral math, not votes nation wide.
Huckabee bring nothing to the ticket in terms of electoral math. Neither does Gingrich, Huntsmen, Perry, etc.
Alan West gives him a shot at FL as well, but he doesn't have the popularity that Rubio has.
He may also be looking at a younger, less established conservative woman to help in states like Ohio and NC. There are a couple in congress but they are only if Rubio really tells him no.
