If Bush is accountable then so are the conservatives who cheered after Roberts was named.
No, Roberts didn't magically appear. He was lobbied for...conservatives worked hard to bring his name before Bush. His name was put forth time and time again right here on FR before Bush ever named him. And FR celebrated when he did.
It wasn't the RINOS who pushed hardest for him to be on the court.
We'll never know now if it would have made any difference, but FR leadership spent most of the Bush years in a paranoid witch hunt to sniff out and purge any criticism of the demented neocon juggernaut. Some of the brightest and most fearless voices were driven out or else bullied into silence both here and elsewhere throughout the (nominally) conservative movement. The result is that today "conservatism" in America is largely adrift, unprincipled, reactive, philosophically impoverished, anti-intellectual, ignorant, and angry. Obama's indisputably the worst-ever POTUS, but Dubya's right behind him, and FR played its part in allowing him to commit his folly unchallenged.
