Lott is not being railroaded, he brought this on himself. His homage to Thurmond as Dixiecrat wasn't vague, it was stupefyingly ill-advised at best. He had opportunities to get out in front of this early, and failed, and failed, and failed again.
Playing revisionist (to give Trent the benefit of the doubt) with the Dixiecrats is a hobby better suited for fringe-types, not our Senate Majority Leader.
