I'm thinking of putting up a bumper sticker, I'm just trying to decide what kind is best.

-A constructive bumper sticker. Something like "Democratic and Proud." "Obama/Clinton/Edwards '08" "Any Democrat in '08"

-A destructive bumper sticker. "No Blood For Oil" "Bush's War" "Republican = Corruption"

-Or A subversive bumper sticker. "Where have all the Republicans Gone?" "Bush has destroyed the Republican Party" "McCain in '08" "These aren't real conservatives" "Ron Paul in '08"

I trying to decide which one would do the most good. I don't care so much about proclaiming my beliefs as maybe changing a mind or two. Keeping in mind I live in Northern Nevada, which is rather conservative, what might be the best approach?
