The organizations said their funding represents “the largest coordinated-side commitments to date in North Carolina, Michigan and Florida for the 2020 cycle.”

Under former President Barack Obama, Democrats lost more than 1,000 state and congressional seats. The devastating losses left many Democratic activists and insiders believing that they needed to do more to focus beyond the White House.

“That’s the lesson the radical right has taught us over the last 45 years,” said Ravi Gupta, co-founder of Arena. “So much of what is going on depends on the states.”

Arena and Future Now Fund are expecting to place more than 100 staffers in the four targeted states, hold five-day training academies for 150 aides in each of them, and provide funding to candidates and related groups. Most of their funds will be raised at the grassroots level, the liberal groups said.

Leaders for the groups said they chose those four states in particular for the joint project for several reasons: They think Democrats are poised to win them back, and that each state has faced voter rights or redistricting issues, such as gerrymandering in North Carolina.

They also want to address specific issues in those places, including low teacher pay in Arizona and the water crisis in Flint, Michigan. And they are looking to take power in the states ahead of redistricting following the 2020 Census. The GOP prioritized its redistricting efforts to great success after the last Census, and the two groups are looking to emulate those results.

“There is the potential for significant positive impact on redistricting,” said Gupta.
