The real danger is that those who defend Obama the Candidate no matter what he does are likely to defend Obama the President no matter what he does, too. If we learn in 2009 that Obama has invoked his claimed Article II powers to spy on Americans outside of even the new FISA law, are we going to hear from certain factions that he was justified in doing so to protect us; how it's a good, shrewd move to show he's a centrist and keep his approval ratings high so he can do all the Good things he wants to do for us; how it's different when Obama does it because we can trust him? It certainly looks that way. Those who spent the last five years mauling Bush for "shredding the Constitution" and approving of lawbreaking -- only to then praise Obama for supporting a bill that endorses and protects all of that -- are displaying exactly the type of blind reverence that is more dangerous than any one political leader could ever be.
