Nope, not kidding. According to the Arizona Daily Star, the senator who so loves evangelical Christians is part of a cover story in the infamous men's mag (and has some interesting company):

In the same issue as a pictorial of "The Real Girls of Orange County," McCain--along with a number of regular citizens, celebrities and political figures--writes about why he thinks we're in Iraq.

And the New York Sun has the details on the content:

In an essay for this month's Playboy, Mr. McCain wrote, "Fundamentally, I agree with the neoconservatives because I believe we can do a better job of helping people achieve democracy and freedom." However, he said serious questions exist about whether neoconservatives exaggerated the threat posed by Iraq.

An EFM fan--who heard about the story via today's Hotline--comments:

I’m having a hard time with someone who wants to be Commander-in-Chief spreading his foreign policy views in a magazine that objectifies women. I don’t believe the line that people “read it for the articles.” If you want to read it for other purposes, fine, but don’t pretend it’s anything other than it is--a magazine with pictures of women in various stages of undress.

Well, I actually don't think the "other purposes" are okay whether you're pretending or not, but the point about honesty is well taken.
