Based off of that piece of information... can considering the similarities between Santorum and those two... I would hazard that when Santorum does drop out of the race, he will endorse Romney as well.
Both Ricks being CONSERVATIVES will endorse Speaker Newt who they both have said they admire.
Willard the LIBERAL will get Charlie Crist though. Woo hoo!
Jeb Bush and Huck will wait till the Tampa convention for obvious reasons.
The Santorum die hards really do not like Mitt, that is why they are still supporting Santorum as an anti Mitt. I do not see those supporters flocking to Mitt if Santorum endorses Mitt.
So that endosrement, should it occur, will be of little benefit to Mitt.
They (supporters) may have their sails deflated though.
