That's because he is an American. He's lived here since 1982, and became a citizen in 2000.
Thanks. I didn't know the exact details, but that was the point I wanted to make to those who kept calling him a Canadian who had no business involving himself in US politics - that he *is* an American citizen and voter.
I wouldn't trade places with him for anything, so I didn't want to join the rock-throwers. I just disagree with his position, and I'm sure he's desparate for anything that will help him and others in his situation.
