“and if Rubio is on the ticket I feel he would veer Romney in the right direction”
I may or may not agree with your definition of politicians. However, do you really believe that they would both advance the same policies? Why do you care if the president is being “sincere”? If you believe that neither is sincere, but one of them will insincerely advance policies that will be better for the country, wouldn’t it make sense to vote for him?
Also, why do you believe that Rubio would have such great influence over a “blood sucking creature”?
