How is a bumper sticker going to change how someone is going to vote this November?

I believe them to be somewhat annoying. Also, they would likely invite people with differing opinions to deface/damage said bumper or car. Something to think about I guess.|||They are dum.|||I totally agree. I have no idea why people want to advertise their political beliefs with bumper stickers and yard signs. I find it very tacky.|||ITS NOT THEY ARE TO LET OTHERS KNOW WHAT YOU THINK AND TO P O OTHER PEOPLE|||People with bumperstickers are just passionate and excited about the elections, that's all.
