Just to be safe, how about putting a few McCain-Palin bumper-stickers on Obama supporters’ cars...
I keep a few extras in my car. I'm waiting until I see one of those cars with tons of Obama stickers/Anti-American stickers on it, then I'll do it!
That IS the solution: put a McCain/Palin sticker on an Obama-supporter’s vehicle and you’ve created a vote for McCain, after they get a 1st-hand taste of what their Obama-friends are REALLY like.
