REDMAP is a project of the Republican State Leadership Committee of the United States to increase Republican control of congressional seats as well as state legislatures, largely through determination of electoral district boundaries. The project has made effective use of partisan gerrymandering, by relying on previously unavailable mapping software such as Maptitude to improve the precision with which district lines are strategically drawn. The strategy was focused on swing blue states like Pennsylvania, Ohio, Michigan, North Carolina, and Wisconsin where there was a Democratic majority but which they could swing towards Republican with appropriate redistricting. The project was launched in 2010 and estimated to have cost the Republican party around US$30 million.
