In yet another indication that Senate Republicans are really playing on defense everywhere this year, a new Rasmussen poll has bad news for them in even the deep-red state of Mississippi, with appointed Sen. Roger Wicker (R) now trailing former Gov. Ronnie Musgrove (D) in a race that's within the margin of error:
Musgrove (D) 47%
Wicker (R) 46%
Sample size: 500 likely voters.
Margin of error: ±4%
