From Capitol Hill to the statehouses to the presidential primary, Republicans are turning their back on almost every important accomplishment of the Bush administration.Bush’s attempt to reposition the GOP to the center-right has been rejected in favor of an unmodified brand of conservatism that would rather leave people alone than lift them up with any “armies of compassion.” Many of Bush’s distinctive policy ideas have fallen by the wayside, replaced by a nearly single-minded focus on reducing the size of government. Twelve years after the then-Texas governor chastised his party’s congressional leaders for attempting to “balance their budget on the backs of the poor,” it’s unthinkable that any serious Republican presidential hopeful would attempt to get to the left of the congressional GOP. As Bush’s successor in Austin illustrated in a jeremiad at a Republican conference here this weekend, potential White House hopefuls now are competing to prove their conservative bona fides — and any criticism of their own party is for its purported drift away from principle. “It saddens me, sometimes, when my fellow Republicans duck and cover in the face of pressure from the left,” Texas Gov. Rick Perry said in his red-meat-filled address Saturday. Republicans now openly condemn the bailout programs Bush initiated for banks and auto companies. Members of Congress look on the No Child Left Behind Law with suspicion. Few will defend the Medicare prescription drug benefit, and the only acceptable party line now on immigration reform is “No Amnesty.”
