BUT... he once gave $20 to Obama's campaign.
Hopelessly biased.
In today's world, unfortunately, this does show bias. You can't donate one way and then go after the other side - even if there is no ill intent, the polarization of society will cast doubt upon your actions. So you have to find someone who is apolitical otherwise the other side won't accept it. And don't make this a right/conservative thing. The moment the sides switch, the left would be claiming the same problem, and they'd be right.
