For the 2010 elections, Republicans created the Redistricting Majority Project (REDMAP) with the plan of flipping state legislative chambers to take control of the redistricting process. Did the Democrats have a similar organization, and if so what was it called?
(Note: I don't consider the DSLC an equivalent group, as the Republicans also had the RSLC in 2010 but that never seems to get mentioned in analysis.)
