How many years in national gov't did W have? or Clinton? or Reagan? or Carter?
All had at least six years as Governor before taking office, three of them in some of the largest states in the country. Obama has two years serving in the Senate, four by the time he'd take office. No President, hell, no major party candidate for President has had less experience before taking office. Let Obama simmer in the Senate for at least one re-election campaign and see whether he actually is something more than charisma in a suit.
