The Politico has more info/speculation on the Senate GOP leadership races:

Sen. Jon Kyl (R-Ariz.), clearly has the No. 2 spot vacated by Lott wrapped up without any opposition.

And even the Senate Republican Conference chairmanship may be less of a free-for-all than originally expected. The No. 4 and No. 5 positions within Republican leadership may also be determined without much of an internal struggle.

Sen. Kay Bailey Hutchison (R-Texas) is being touted by several Republican offices contacted by Politico as the front-runner for the conference chairmanship, despite the entry of Sen. Lamar Alexander (R-Tenn.). Alexander's office begs to differ, saying they're getting positive response from many Senate offices.

Sen. Richard Burr (R-N.C.), a conservative upstart, has yet to officially enter the conference chairmanship race and may not place his name on the ballot if he doesn't have a clear shot at winning, according to several GOP aides.
