So people are interested in the presidential race, and this presents a great opener, my caucus opener killed this January.

Many variations possible but the one I use is at night:

-Could you settle a bet between my friend and I? (Either Obama-Clinton, or Obama-McCain) People will talk about this for a while.

During the day:

-I'm testing my guessing everyones candidate (then)
you look like a XXXX supporter
OR I want to say that you are a XXXX supporter but I get the feeling that you actually are a XXXX

Notes:
-Go with Obama and be safe, especially if on campus
-If they say I don't know, there is your neg and go into your stack.
-If you are really confident go back to primary, throw in phrases like "bat shit crazy XXXX" (here is usually put in ron paul, mike gravel, or dennis kucinnich

I can add more if anyone wants it, just PM me and add to this post and reply as well.
