Last night the late night comedy shows featured potential GOP candidates that might face Barack Obama when he comes up for re-election in 2 1/2 years time.

Sarah Palin appeared on NBC's Tonight Show with old host Jay Leno, while Mitt Romney went on David Letterman's Late Show to hawk his new book, No Apology: The Case for American Greatness.

On Leno, Palin said she's keep writing notes on her hand to "Keep the left all we-we'd up"

But while those potential candidates try to get their message out via their memoirs, there's another potential candidate on the loose.

New York City Mayor Michael Bloomberg, that is.
