Palin also endorsed Rick Perry in 2010 over K. B. Hutchison.
And you have a problem with that?
Yes, she sure did. God bless Sarah Palin.
I'm no Perry fan, he has sleazy rich friends .... but at least his friends don't include the Bush dynasty. Bush Sr. regards Perry as unreclaimed white trash, a scarcely-ameliorated Klansman in a business suit. So people say, who are in a position to know. Generally speaking, Bush people don't like the Democrats who crossed the aisle in the 80's and consider them all Dixiecrat racists.
KBH on the other hand, came up from TV journalism (she was a Dallas-area news anchor before she tried politics) and has always been a Bush "good government" Republican, with an ACU rating somewhere in the 70's or 80's, not quite as high as John McCain's before he began "drifting to the middle" and thinking about the Presidency.
And she's always been solidly pro-abort, which is what IMHO finally chased her out of politics.
