The thing about Rubio is that he is dishonest. With Jeb you know upfront he does not agree with you on the issues. He is more openly liberal than his brother was. At least that respects republicanism and the voters right to make an informed choice. Rubio campaigns one way and then joins with the democrats to plot against the principles he campaigned on. Then he has the gall to flip back while campaigning for even higher office. It is the lack of trust.
You’re saying Rubio is more of a backstabber than his former mentor Jebbie. Maybe so, but I would rather take a chance on Rubio if we have to do so than on Jebbie or any other of his family members.
