From the NBC News political unit
NBC News projects that Republicans will gain a majority in the House.
The new Republican majority means the ouster of Nancy Pelosi as Speaker of the House, with the likely election of Republican John Boehner of Ohio to replace her in the chamber's highest post. It will put the GOP in charge of the lower chamber. Republicans have pledged to introduce legislation that could partially unwind the reforms passed under the Obama administration.
NBC's projection is that Republicans will hold a 236 to 199 seat advantage in the next House of Representatives. The margin of error is plus or minus 13 seats.
Republicans needed to win 39 seats to regain the majority in the House.
Democrats gained 32 seats in the 2006 cycle and 24 seats in 2008. The GOP wave makes 2010 the third "change" election in as many cycles — only the third time that has happened since World War II.
