There are a large number of Obama supporters that HATE free speech. They cannot stand the idea that someone would think different than they. They especially don't like it when someone comes along that can show the hollowness of their faith.
They will burn
, and vandalize
anything that is pro McCain.
They simply do not want the competition nor the First Amendment - unless it applies to them.
While it is true
that it happens on the other side, just a quick browsing of the Internet shows more McCain/Palin signs being vandalized than the reverse.
If you destroy, steal, or vandalize a yard sign, you are NOT helping your party. You are participating in a crime. I hope you get caught. I hope you get punished.
Leave the signs alone.
