Based on this Washington Post article, Obama's "audacious hope" really rings of naivete, and an unrealistic expectation of how things truly get done in Washington. "Sweeping bipartisan change" is an oxymoron; "change," sweeping or otherwise, typically occurs only when one set of partisans has enough votes to ram it through over the objections of the other side. There are exceptions, such as LBJ's civil rights legislation, which could not have passed without Republican votes, but given how polarized the parties are these days, I sincerely doubt it will matter how charming and inspirational a President Obama would be. Republicans have already settled on their game plan, obstructionism, and I don't see that changing, no matter how badly they get whipped in November.
In other news, just in case the historical relevance of the word "populist" hasn't yet been sufficiently desecrated through association with such odious poseurs as Ron Paul and Mike Huckabee, now Lou "Crazier'n a shithouse rat" Dobbs is mulling a bid for President to hold the line against the Invading Brown Hordes.
UPDATE: Senator, I knew Jack Kennedy; Jack Kennedy was a friend of mine...
