Some of them are atheists/agnostics while others are average (read: half-assed) Christians who maybe go to church a few times a year and rarely pray or read the Bible, etc.
At any rate, most of them don't take Palin seriously. Meaning they don't think Palin as VP (or even as president) will make a difference on issues like abortion. They say "no way Roe V Wade will be overturned". These are pro-choice types who think they're being fiscally smart by supporting McCain.
They're wrong of course, but I'm amazed by the fact that they think Palin is harmless (and hot). And for the record yes, she's an attractive older politician...honestly, she wouldn't be generating half as much positive press and interest if she wasn't.
