Koch Brothers relation, but that will be thrown at virtually any Republican.
His record? From what I understand, Wisconsin's still running big deficits. I'm not familiar with whatever else may be wrong with the state's economy.
Even among Republicans, there seem to be few who can match Walker when it comes to Koch-sucking.
When people talk about his record, I'd guess they're thinking more of things like cutting hundreds of millions from university, while giving $200 million to a pro basketball team.
