Ahh, another suicide Republican comes out from under a rock.
One of the reasons the democrats (and the media) are pushing this so hard is to try and force Republicans to circle the wagons in support of Sen. Lott. Their fondest wish has to be that Lott is kept as leader. Secondary to that would be for Lott to be put aside AND resign his seat.
The President and his people, and the Republican caucus in the Senate, have to (quietly) manage this so neither wish is granted.
