It's difficult to say whether the bumper stickers help or not. I'm encouraged by some of them, and often reminded of what's important.Agreed. But I take my anger and concerns to the polls when it comes time to vote. I talk to the uninformed voters as much as I can to explain things because I know they don't understand politics. And yes, I go to these blogs.
If I thought that a bumper sticker would do any good, I would put them on my car too. But bumper stickers won't change the vote of one person. All it might do is cause your car to be damaged. Either way, you accomplish nothing. It's just like those paper ribbons people put on their cars to support our troops. Did any one of those ribbons help one solder?
Our Constitution gives us freedom of speech, but some of our fellow citizens believe freedom of speech only applies to them.
Politically-speaking, I tend to buy stickers that have something poignant on them -- not inflammatory. There were quite a few people who honked and waved when they would pass me during the election season -- I'm assuming because I had a conservative sticker on my car. I think it's good for people to see there are folks who will publicly make a stand.
