Hillary Clinton beat Barack Obama by double digits in Pennsylvania. She seems to have the momentum now, though it will be nearly impossible for her to overcome Obama’s lead in delegates, which he racked up earlier in the campaign. Back then, he was a breath of fresh air, promising an end to ideological warfare, transcending race, and embodying a politics of hope. Lately he has been coming across as just another liberal politician. Racial divisiveness is back in politics, as is the old class warfare that Democrats always seem to want to wage and always seem to wage in a way that it backfires on them. Part of the problem may be the Clintons backing him into these corners. Also, now that he has become the candidate of choice of the party’s harder left, they may be affecting his rhetoric. But is there a way for Obama to get back to his original image?
