I think he is saying this partly tongue in cheek. I meet him in Metropolis, IL earlier this month. The guy is hilarious. He was asked about playing Lex in a movie in front of the huge crowd at the Superman Celebration. He was relishing the cheers when a fan asked that. Acting like he was campaigning for office jokingly. I think that weekend spurred this. I am sure he do it if he could but he is mostly taking about this for fun.
