It's fitting that the first post-election column by an elected Democrat would be from Indiana's lame-duck senator, Evan Bayh, whose calling card is inoffensive, business-friendly centrism. His explanation for Tuesday's Democratic losses -- "Democrats were too liberal" -- is likely to be the standard one going forward, for the simple reason that it's easy. Whenever Democrats suffer an electoral loss, moderates and conservatives flood the nation's op-ed pages with a torrent of editorials blaming the left for the party's losses, declaring that this is a "center-right nation" and that Democrats should have never bothered governing.
