No, its like joining the Navy, and deciding after two years you'd rather be a SEAL.
I'd be inclined to agree that two years isn't a lot of experience. So how would he compare that to a guy who's never been a governor, never showed up for work as a state senator, and has been a US senator for all of a hundred and some-odd days? If he were running as McCain's vp, I'd be worried because he has almost no experience at all, and what experience he has he keeps trying to hide.
Well, this is the guy who puts out there that running for President gives him the experience needed for being President. Makes alot of sense, huh?
