See, there you go again.."potential" tax dodger. You're just assuming he's dodging taxes because he refuses to show his taxes. This is the typical leftist thought process. Guilty until proven innocent. Sorry, but that isn't the way it works here.
If he were dodging taxes he would have been caught by now by the IRS. As high profile as he is and was in the past, there is absolutely no way he'd be getting away with it this long. He's paying taxes and you and the rest of the left hate him so much, you just make shit up and hope it sticks.
