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.
His only failure was to get into politics in the first place.
Try a little mental exercise!
Pretend that you were at the birthday party and try to find a way to compliment the 100 year old fart without the possibility of someone making a issue about it!
I did, and I failed every time.
Lott's only other option would have been to not show up.
