Not a criticism but how would Rubio rock the boat? Guy seems pretty grounded to me, not hard right and well spoken.
I will be honest I missed the Rubio part in the comment and I agree with you. I don't agree with Rubio on some key issues (I know try to suspend the disbelief) but I don't see how he rocks the boat. Unless that boat is rocked by the Republican party selecting a person who is not white, Rubio supports many of the planks of the GOP platform and is able to do so in a professional and non-belligerent tone which many of our politicians can't grasp.
Do I want Rubio or Romney in the White House, absolutely not (again try to suspend the disbelief), but would I fret over a Rubio being the VP, again no.
