Mickey Kaus makes some good points. "GM's stock is in the basement for a reason" would make a good political bumper sticker or debate point. And just as a reminder what the GM bailout entailed - and how they really haven't paid the taxpayers back - here's a good minute and a half primer from Reason TV.
I'll make a prediction right here - during a Presidential Debate President Obama will say or claim something that will cause the stock of GM to sharply decline even further. Something like the government will be selling (dumping) its share in GM by the end of the year or something like that.
