When my cousin in law starts going off about Republicans I now just laugh and say "You guys pinned all of your hopes on Obama!!!!" Then laugh until I almost pee my pants.
When I am around hussein supporters I start doing my imitation of the Rush commercials: "The past is the past and it isn't the future, which is hopeful. So hope for hope and I will give yo uthe hopeful future -- and that is hopeful."
Then, time permitting, I ask how that differs from the message of a junior Senator who has voted "present" and has never had a real job in his life. I usually get nervous Bush bashing. There usually isn't time for proper making fun of BDS.
