Why, this man, of course:

I’m not gonna tell you I wasn’t a huge fan of Rich Little when I was a kid; truth be told, I can still remember watching “Rich Little’s Christmas Carol” on HBO and loving every minute of it. But, c’mon, was the backlash from last year’s entertainment at the White House Correspondents Association dinner – Stephen Colbert – so tremendous that they had to find the cleanest, most mainstream political comedian (and I’m using the term loosely) to follow him?

Apparently so.
