Mississippi Democrat Travis Childers won a special election to Congress on Tuesday, helping his party to a third victory in recent months for seats long in Republican hands.

The victory puts Childers into the seat vacated by Roger Wicker, a Republican appointed to the U.S. Senate when Trent Lott resigned. The win also pushes the Democrats to a 236-199 majority in Congress — if only for a few months until November's general elections.

With 99 percent of the precincts reporting, Childers had 54 percent to Republican Greg Davis' 46 percent.

At a campaign event in Michigan, Barack Obama spoke about the Republican loss in Mississippi. Obama said, "This is a hardcore Republican seat and they lost it by 8 points. They did everything they could. They ran ads with my face on it. They said look at this liberal. His former pastor said offensive things. They were trying to do every trick in the book to try to scare folks in Mississippi and it didn't work."
