Assuming Obama/Biden wins,
Sarah Palin is John Edwards, the young populist ex-vice presidential candidate.
Bobby Jindal is Obama, the last great non-white young hope for a defeated party.
Who is Hillary in this scenario? I would guess Romney, seeing as both are slick establishmentarians with experience but ultimately not all that likable.
Sarah Palin isn't really populist, but I suppose what you say makes sense.
She is. Populism has no specific ideology (although some are less conducive to it than others).
