I'm tempted to fly up there just to see this. It could really be a lot of fun.
Maher is an absolute moron, and Coulter is the playground bully. I suspect that she's going to take his milk money, eat his lunch and bitch slap him. Of course, we're talking New York City, so she's not exactly going to have a significant fan base. He's a dipshit C-rated comedian along the lines of Franken, who might just draw enough of the dumbass deadbeat "victim" class to fill the audience.
As for your comments about agreeing with both of them 50% of the time, I'd love to understand what you guys agree with Maher about and disagree with Coulter about. That ought to make for some good fun and lively debate.
