Rick Santorum Endorses John McCain?

Today, former Pennsylvania Senator Rick Santorum held his nose and, while not doing him any favors, endorsed Senator John McCain for President.

I've disagreed with him on immigration, global warming and federal protection of marriage. I've taken strong exception to his view that the federal government should fund embryonic stem-cell research.

[...]

Yes, I often wished McCain would have joined me on the Senate floor in debating Barbara Boxer on issues like the partial-birth-abortion ban.

[...]

Yes, I disagreed with McCain's opposition to President Bush's tax cuts in 2001 and 2003.

[...]

And, yes, McCain has been a thorn in the side of many of us who supported important appropriations earmarks for our states.

Never mind that Santorum painted McCain as an unelectable liberal earlier in the primary season, when he was supporting Mitt Romney.

My favorite reason why Santorum says he's supporting McCain:

He's not Barack Obama or Hillary Clinton.

Now there's a ringing endorsement.

With friends like Rick Santorum, who needs enemies?
