The latest polling in the Mississippi Senate race has incumbent (albeit appointed) Sen. Roger Wicker (R) now trailing former Gov. Ronnie Musgrove (D), 47-46. This is the race to complete the term of the retired Trent Lott.
[ed. note: This post originally had the spread as 44-40, which is actually the number from the latest poll on Obama v. McCain in Michigan, where McCain is leading. So many polls. Sorry for the confusion.]
