I'd also love to see Norm MacDonald hosting one of these shows, but it'll never happen. He's seen as too much of a loose cannon, and frankly he's not of the political persuasion CBS would be looking for. Nor ABC, nor NBC. They'd never get him to agree to not tell Obama jokes like all the others (and I'm willing to bet that's why Leno started making Obama the butt of a lot of his jokes, because he was being pushed out by NBC anyway and had nothing to lose). I don't know if anyone's paid enough attention to notice, but despite Obama being great fodder for punchlines, Fallon, Kimmel, Meyers, and Letterman have avoided joking about him like they'd be shot if they did. I'm sure O'Brien also has avoided telling Obama jokes. MacDonald, on the other hand, would NEVER stop, and if you told him not to do it he'd do it more just to rub your nose in it. He's also never been keen on being politically correct, another danger zone for the networks.
