Reason Magazine polled “policy wonks, journalists, thinkers, and other public figures in the reason universe.” John McCain is highly unpopular among them. Some highlights:

Drew Carey:
“Anybody but McCain/Palin. Seriously. I’m begging you.”
Comedian and Magician Penn Jillette:
“Bob Barr, he’s the Libertarian, right? I like people to know there are some of us out there.”
Craigslist Founder Craig Newmark
“Barack Obama, since he’s a genuine leader, with a good program for cleaning up Washington, and will be very good for business.”
Author Bruce Bartlett
“I plan to vote for Obama mainly because he is not a Republican and not John McCain, who is temperamentally unfit to be president.”
Reason magazine’s Jacob Sullum
“Bob Barr. I admired Barr as one of the most libertarian members of Congress even when he was a Republican and a gung-ho drug warrior. I respect him more for having the courage to publicly change his mind about drug policy and, more broadly, about the wisdom and propriety of using the federal government to impose a socially conservative agenda on the country.”
Reason Foundation Founder Robert Poole
“John McCain, as the less-bad option. I base this on his positions on free trade, taxation and spending, unions, and Supreme Court nominations, as well as the merits of divided government (given the near-certainty of strong Democratic majorities in both houses).”
