Don't be so critical of Romney. He made a fantastic choice in Ryan as VP. That alone should prove that there are some secret conservative sinews inside the old Mittster.
Do you think that the lifelong pro-abortion Romney, hated Reagan’s conservative politics and left the GOP in 1979, because the lifelong pro-life Reagan, signed that bill in 1967?
That is a silly attempt at an explanation, you know very well that Romney hates conservatism because he is liberal, he had to choose someone to balance the ticket.
The liberal Romney chose someone who is conservative, and the conservative Reagan, had to choose the Romney of his time.
