He already has the nomination. He doesn’t need to “cement” a damn thing.

Conservatives outnumber Liberals - by a large margin. If he choses a lukewarm RINO, he will lose a lot of the base. They simply won’t bother to vote (as they have time, and time again).
However, if he energizes his base - the numbers of Conservatives voting a Romney/Palin ticket would outnumber the voter fraud the DNC is probably already orchestrating.
