A Democratic group backed by former President Barack Obama intends to pour millions of dollars into an eclectic array of elections in a dozen states, in an effort to block Republicans from single-handedly drawing congressional maps after 2020, officials leading the group said.
The National Democratic Redistricting Committee, formed last year under the leadership of Eric H. Holder Jr., the former attorney general, has settled on a strategy to contest a combination of governorships, legislative seats and more obscure state offices to chip away at Republicans’ sweeping control of the redistricting process.
Mr. Holder said in an interview that the group was chiefly determined to deny Republicans so-called trifectas in state governments — places where a single party controls the governorship and an entire legislature, as Republicans do in Ohio and Florida, among other critical battlegrounds.
The group’s list of high-priority states includes most of the critical states in presidential elections. Mr. Obama, who has made redistricting a focus of his attention since leaving office, plans to visit some of those states in 2018, and Mr. Holder reviewed his strategy with the former president in Washington on Monday, aides said.
States at the top of the just-finalized target list include traditional purple states like Michigan and Wisconsin, where Republicans can currently design maps without Democratic input, and others — including Colorado, Minnesota and Nevada — where Democrats have significant influence in government but must defend it in the 2018 elections.
