rtr1yqkf.jpgWASHINGTON – Democrats captured another Republican seat in the U.S. House of Representatives on Tuesday night during a special election in Mississippi, the third such victory this election cycle.

Yet another loss will likely strike fear in the hearts of many Republicans who are worried that it could have even bigger ramifications this November as they try to claw their way back to a majority.

In the race to represent northern Mississippi, Republican Greg Davis lost to Travis Childers despite a last-minute effort by Vice President Dick Cheney to woo voters at a campaign fundraiser for Davis on Monday. Childers will have to run again in November, this time for a full two-year term.

He will fill a seat vacated by Rep. Roger Wicker who was appointed to fill Sen. Trent Lott’s seat and expands the Democratic House majority to 236-199.

“His victory has sent a thunderbolt across America tonight,” said Rep. Chris Van Hollen, a Maryland Democrat who is chairman of the Democratic Congressional Campaign Committee.
