Um, we're not the ones using Demorcrat-style nitpicking here. And if you go to Kuester's website, you'll find that he's against "Smart Growth", which basically tears up the rights of private property owners.
His opponent, a Republican, is in favor of misuse of eminent domain. Doesn't sound very "conservative" to me.
His Republican opponent (Sheryl Albers) seems to me to be acceptably conservative...and I fancy myself a strict-constructionist. I live in their district and would make a great libertarian, but I feel that the libertarians and republicans should duke it out only after the liberals have been dispatched...and that ain't gonna happen anytime soon here in the peoples republic of wisconsin, til then, voting libertarian will only help elect demons.
