(CNN) - CNN projects Republican Sen. Roger Wicker held on to his seat Tuesday night, winning Mississippi's special Senate election.

Former Senate Majority Leader Trent Lott's appointed successor had faced a tough fight from former Democratic Gov. Ronnie Musgrove. Party identification is not included on the ballot in Mississippi, so a projected surge in African-American and Democratic voters was not expected to have the same impact as it did elsewhere.

Sen. Mary Landrieu (D-LA).

(CNN) - CNN is projecting that incumbent Mary Landrieu has won re-election in Louisiana.
Landrieu held a dubious distinction this cycle as the only Democratic senator to face a real re-election threat. The two-term senator - whose two victories have been won by razor-thin margins - faced her toughest opponent yet in state Treasurer John Kennedy.
The Democrat-turned-Republican had the support of Louisiana's popular GOP governor, Bobby Jindal, in a state that strongly supported John McCain.
Republicans had poured hundreds of thousand of dollars into ad buys in the state, pointing to last-minute poll numbers that suggested the race was tightening. But the cash-rich Democratic Senatorial Campaign Committee spent even more, and Landrieu entered Tuesday a heavy favorite.
