Maybe I'm different but negative campaign ads bother me. Many are based in half truths and deception and in those cases I'm actually offended concluding the candidate running them thinks I'm too stupid to spot dishonesty when directed at me. I realize there are strong supporters of any candidate or party and I understand those people cheer the negative campaign ads bashing their guy's opponents but I thought ads were designed to persuade undecided voters or get people to change their minds.
There's a local ad running right now attempting to unseat an incumbent. The incumbent promised to not raise taxes. The ad claims he broke his pledge because taxes went up. Truth: the candidate did not raise taxes. They were based on property values and because property values went up, so did property taxes. If the cost of gas goes up, so will the embedded gas tax. This doesn't mean the government "raised" gas taxes.
