Swing Left was launched in 2017, as the first Women's March dwarfed the crowd at Donald Trump's inauguration. Its immediate goal was winning back the House as a check on Trump’s power. Beyond that, it created an organizing strategy that gave activists and small donors a flexible, effective way to partner with people on the ground in the swing districts where key electoral battles would likely be fought.
The response was immediate and overwhelming, as I reported that same month, and the results in the 2018 midterms were similarly impressive: Out of 84 districts targeted by Swing Left, 16 stayed blue and 39 flipped from red to blue, accounting for all but one of the 40 Democratic pickups in that cycle.
