"Swanson’s story has its counterparts all across the nation—most importantly, in districts like hers that could swing Democratic in 2018. In the Republican Representative Ryan Costello’s suburban Philadelphia district—which, like Comstock’s, was carried by Clinton—Claire Witzleben, a stay-at-home parent with a master’s degree in health-care administration, has been organizing weekly protests since mid-January outside Costello’s district office in West Chester. One week the protest topic is Trump’s alleged connections to Russia, the next it’s the president’s deportation plans or the ACA repeal. Before the election, Witzleben admits, she didn’t know the name of her representative or even what district she lived in. Trump’s victory, she says, quickly woke her up. Now, Witzleben and Tammy Harkness, an engineer, are the lead organizers for one of the area’s local Indivisible affiliates, dubbed the Concerned Constituents Action Group, which organized a town hall meeting for Costello on the last Saturday of Congress’s President’s Day recess. For both women, this was their first time engaging in political organizing.
Costello’s Sixth District, as Democrats describe it, “looms like a dragon descending on Philadelphia from the west,” carving jaggedly through the towns of suburban Chester, Berks, Montgomery, and Lebanon counties. It’s a mostly white district that mashes up very wealthy suburbs with more rural pockets—and one that Republicans have held, despite consistent targeting by Democrats, since redistricting in 2000. Costello, a second-term member, wiped the floor with his Democratic challenger in 2016, winning by 14 points. However, Romney-voting Republicans ditched Trump en masse, giving Clinton a narrow victory in the district of just over one-half of one percentage point. If that didn’t put Costello on notice, he’s now feeling the heat from organized constituents as well".
