Santorum hasn’t needed any help lately in giving people reasons to bash him.
Santorum is still in the running even though it is a long shot that he will ever catch Romney. Still, it is a two man race.
So it is a realpolitik axiom that a hit on Rick is a kiss on Mitt.
Now if someone is a Mittbot, I could respect their bashing Santorum—at least they have some integrity even if their man is a serial liar RINO.
