Karl Rove appeared on Fox News' America Live Monday morning, slamming the Texas governor for even dealing Donald Trump, who's openly questioned whether President Barack Obama was born in the United States.
"Don't associate yourself with a nutty view like that and you damage yourself," he said. "I know he went and is trying to cultivate and all to get Donald Trump's endorsement. But this is not to way to go about doing that because it starts to marginalize you in the minds in some of the people you need in order to get the election."
Rove, who has never had warm feelings for Perry (and vice-versa), added: "There's a simple answer: Yes, he (Obama) was born in the United States. Yes, he is eligible to serve and don't associate yourself with this nutty fringe group."
In fairness to Perry, he didn't give a full-on embrace of birtherism, calling the matter "a distractive issue.”
