OK. I was inspired by comments on bumper stickers on the American Way of Life thread. Decided not to add to that chaos. Checked for old threads. Saw nothing appropriate. I am operating under the broad definition of political. I see, on a '01 thread, that some people hate them. Some like them.

I looked at my new silver coloured car, three years ago, and said, "Wow, a tabla rasa!" It has been referred to as a "moving political statement". When parked, people often take time to walk all around it, reading. None are on the bumper.

A CLOSED MIND IS A WONDERFUL THING TO LOSE. (my fav)
QUAKERS FOR OBAMA
WELL BEHAVED WOMEN RARELY MAKE HISTORY (on the driver door, lest anyone mistake.)
    (And it has already been pointed out that it is sexist but both men and women love it. Someone actually asked to photograph it recently.)
UNITED FOR A NON-TOXIC MILLENIUM
CHOOSE LOVE
IT WILL BE A GREAT DAY WHEN OUR SCHOOLS GET ALL THE MONEY THEY NEED AND THE      AIR FORCE HAS TO HOLD A BAKE SALE TO BUY A BOMBER (Old but still valid)
THERE IS NO WAY TO PEACE, PEACE IS THE WAY
GIVE PEACE A CHANCE
YOU CAN'T HUG A CHILD WITH NUCLEAR ARMS
WE NEED A DEPARTMENT OF PEACE
Today I will commit one act of senseless kindness, will you?

There is room for more but that would be too cluttered for most people to read!
My far right brother lets me park in his driveway! I got in and out of Canada in April. Whew! I doubt anyone would try to steal the car! I consider it an excellent venue for getting a few people to THINK just a little bit. My favourite feedback was a robust woman who stated enthusiastically, "WE LIKE YOUR BUMPER STICKERS!! AND WE'RE NAVY, AND WE LIKE THEM!!!"

Gosh, I hope they let me into Apple Hollow Music Fest!! PLEASE!
