I have seen Schweikhart's recent advert. And I am wondering: Does he think his audience is stupid? He makes a big deal about how you shouldn't vote for Mitchell be runs negative ads and the rest of the ad is negative things (or, at least, things Schweikhart considers negative) about Mitchell. Whether you agree with his policy ideas or not, it's hard to miss the fact that he is saying you shouldn't vote for people that rely on attack ads while himself relying on an attack ad.
Erratum: It seems that name is Schweikert and I misspelled it.
