Additional Info on that Ron Howard Endorsement Video

I see this morning that Mark Evanier has posted the Opie/Richie clip as well, along with an interesting comment:

...before any of you start muttering about Hollywood Liberals...I've actually talked politics with two of the three men in this video and I would have bet on Cindy McCain endorsing Barack Obama before I'd have put money on these guys...

So which two of the three do you suppose he's talking about? I think Andy's probably an easy bet; his age and background would naturally lead to the more conservative side of the spectrum. But between Ron and Henry (about whom I admittedly don't know much, aside from their public personae)? Hm. That's a stumper...
