I watched Rick Santorum’s speech dropping out of the race. It runs about 14 minutes. He didn’t mention Mitt once, let alone endorse him.
I know the endorsement will come, but it seemed strange for him to conclude without saying that he was backing Mitt and urging his supporters to do the same.

Nothing strange about Frothy declining to endorse the empty suit. He probably still thinks that from all his piety, God will somehow put him back in the race. Remember, he only suspended his candidacy, he didn’t pull out.
The suspension is just so he can continue to raise money for his debts, he’s out.
