I think the Cain endorsement is meaningless, too...except that Cain was popular with the Cuban community, so maybe it will pay off to some measure. The endorsement that would help would be that of Rubio, but Rubio is clearly not going to support Gingrich (which I think is a big mistake for Rubio) so that’s out.
The Tea Party did a lot to get votes for Rubio, but I guess even his brief stint in DC has been enough to turn him into Establishment GOP.
Rubio needs to get lots of calls reminding him of this. I agree that a Rubio endorsement for Newt today or tomorrow would help tremendously.
