Anti-Bush people knew their cars would not be trashed by Bush supporters. Anti-Obama folks have to make sure their car insurance is paid up before placing a negative bumper sticker on it (or even one that supports anyone who is opposed Dear Leader. I’ve been keyed.
You are better off putting messages on your car that go over the heads of these liberal fools..
Here are some suggestions:
“A Police State is a Safe State”
“People are too dumb to run their own lives, politicans should run them”
“I love being told HOW to live by smarter people”
“The Liberal Means Justify the Liberal Ends”
“End Politcal Dynasties, Vote Hillary 2016”
“Obama Kept us out of War!”
“Government out of my Uterus, and into my Belly”
“The 2nd Amendment is Outdated, so is the 1st and 4th”
You know, mock them indirectly.
Saw this sticker the other day on a vehicle but it was not mocking it was just lunacy.
“Obama Cares”
If they don't get it, what's the point?
But I love your list.
