Republicans flip 680 state legislative seats seizing redistricting control ahead of 2010 Census

Republicans gain approximately 680 state legislative seats in the 2010 midterm elections, the largest state-level shift since 1928, following a coordinated strategy called REDMAP (Redistricting Majority Project), run by the Republican State Leadership Committee. The RSLC spends $30 million targeting 107 competitive state legislative races in swing states including Pennsylvania, Wisconsin, Ohio, Michigan, and North Carolina. By winning control of 20 states before redistricting from the 2010 Census, Republicans position themselves to draw congressional and legislative maps for the entire decade.
