Larry King interviewed Ron Reagan last night. The full transcript is available here. Here's an excerpt:

KING: You said, dad was also a deeply unabashedly religious man, but he never made the mistake of wearing his faith on his sleeve to gain political advantage. Were you referring to the president?

REAGAN: You know, it's interesting.

KING: Everyone thought that.

REAGAN: I know. I wasn't watching TV much after I delivered the eulogy for a few days. But after a couple of days I started getting calls from people saying, boy you really stirred something up, didn't you? I thought, well, what? Well, you know, the stuff you said about Bush. I said, I didn't say anything about Bush, why would I mention George W. Bush in my father's eulogy?

No, no, no, no, the stuff about the religion. I thought, ha, funny, you then everybody thought I was talking about George W. Bush. And then I heard -- everybody thought I was talking about George -- but people connected with George W. Bush thought I was talking about George W. Bush. And then I began to think, maybe I was, I just didn't know it.

KING: Do you think he wears his religion on his sleeve? He certainly refers to it more than your father ever did.

REAGAN: Well, you know, there was that answer he gave to the question about, did you talk to your father about going into Iraq? No, I talked to a higher father, you know, the almighty. When you hear somebody justifying a war by citing the almighty, God, I get a little worried, frankly. The other guys do that a lot. Osama bin Laden's always talking about Allah, what Allah wants, that he's on his side. I think that's uncomfortable.

KING: Do you have thoughts on the war?

REAGAN: Sure, I have thoughts on the war.

KING: And what do you think?

REAGAN: And I think we lied our way into the war.

KING: You think it's a mistake?

REAGAN: Absolutely, a terrible mistake. Terrible foreign policy error. We didn't have to do it. It was optional. And we were lied to. The American public was lied to about WMD, the connection between Osama bin Laden and Saddam, which is virtually nonexistent except for fleeting contacts. But they're still trying to pull that one off now, Cheney and all are out there flogging that.

KING: Can I gather from that, that you will not support this president?

REAGAN: No, I won't.

KING: Will you support his opponent?

REAGAN: I will vote for whoever the viable candidate is who can defeat George W. Bush, yes.
