George H.W. Bush endorses Romney, because of his "stability, experience, principles. He’s a fine person."

"I just think he’s mature and reasonable — not a bomb-thrower... I’ve got to be a little careful because I like Perry; he’s our governor."

ADDED: By contrast, Rush Limbaugh bashes Romney for declining to call Obama a "socialist."  Romney — responding to Bill O'Reilly's "Is Obama a socialist?" — said:

You know, I prefer to use the term that he's just over his head.  I consider him a big government liberal Democrat.  I think, as you look at his policies, you conclude that he thinks Europe got it right, and we got it wrong.  I think Europe got it wrong.  I think Europe is not working in Europe, and I'll battle him on that day in and day out. But I'm probably not gonna be calling him names so much as calling him a failure.
