Dick Lugar - performance anxiety?

From Harold Myerson's column in today's Washington Post:

Anyone searching for the highest forms of invertebrate life need look no further than the floor of the U.S. Senate last week and this. These spineless specimens go by various names -- Republican moderates; respected senior Republicans; Dick Lugar, John Warner, Pete Domenici, George Voinovich.

They have seen the folly of our course in Iraq. The mission, they understand, cannot be accomplished. The Iraqi government, they discern, is hopelessly sectarian.

In wisdom, they are paragons. In action, they are nullities.

When Lugar made his speech against Bush's Iraq policy, I thought he finally awoke and our not opposing him in the last general election made sense. Not so now.
