Multiplesources are confirming that Mississippi Gov. Haley Barbour will appoint MS-01 Rep. Roger Wicker (R) to fill the vacancy of retiring Sen. Trent Lott today. (Update: It's now official.)
A recent Greenberg Quinlan Rosner Research poll had Wicker trailing former Democratic Gov. Ronnie Musgrove by a 48-34 margin in a hypothetical election match-up. However, longtime SSP commenter Mississippiboy says that Musgrove won't run. I have yet to see published confirmation, but if accurate, Dems would have few obvious choices left on their shelf. Former Gov. Ray Mabus, maybe? (Update: I think we can put Musgrove back in the "uncertain" column for now.)
If Dems can't line up a strong challenger here, state AG Jim Hood's legal fight over the timing of the special election will be made mostly moot.
