With fewer state governments divided by party than in years past, GOP has edge in redistricting

Whenever it happens, redistricting is an intensely, and innately, political process. And when the 35 state legislatures that vote on congressional redistricting get the data they need by Sept. 30 to draw new maps, Republicans will drive that process in 20 states, versus 11 for Democrats, according to a new Pew Research Center analysis. In four states with divided governments, the process could be more complicated.
