It's also telling that Obama can't make jokes about himself. This compounds the fact that he just isn't a very funny person. Bush, OTOH, was a riot and almost all of his jokes were either about himself, or his administration. Obama used the night as a platform to launch political weapons at his enemies. Again, probably not surprisingly.
You’re exactly right. Obama’s jokes didn’t get many, if any, laughs. No surprise as they weren’t funny.
