The most recent one identified itself as the "Republican Majority Coalition".
Interviewer: "If the election were held today, who would you be voting for? John McCain, the Republican, or Barack Obama, the Democrat."
Interviewer: "So, you're undecided?"
Me: "Actually, I'm waiting to see if Bob Barr gets on the ballot here."
Interviewer: (slight chuckle) "I think a lot of people are going to be looking at that as an alternative this year. Thank you for your time."
I don't think that one was particularly legit. But it's fun to get them to check other boxes on their form.
