In Mississippi, one Republicans is safe and the other may be sorry. Thad Cochran, seeking a sixth term, is way out in front, but Roger Wicker, appointed to fill out the term of retired Sen. Trent Lott, faces a tough race to keep his seat.

Cochran leads former state legislator Erik Fleming 58 percent to 35 percent in a poll conducted May 27. Fleming lost to Lott in 2006 by 64 percent to 35 percent. Cochran is viewed favorably by 64 percent of voters as opposed to 24 percent who have a negative view, while Fleming is viewed favorably by 37 percent and unfavorably by 42 percent.

However, Wicker is in a dead heat with former Gov. Ronnie Musgrove. Musgrove leads 47 percent to 46 percent with 2 percent professing other and 5 percent undecided. The margin of error is 4.5 percent in this poll, also conducted by Rasmussen on May 27. Wicker is viewed favorably by 49 percent of voters and unfavorably by 32 percent, while and Musgrove is also viewed favorably by 49 percent with 42 percent viewing him unfavorably. However, Musgrove is viewed very unfavorably by 22 percent compared to 10 percent who have the same strong view on Wicker.
