When Democrats rallied for House candidate Cait Conley in Chappaqua, New York, early Saturday morning, the crowd cheered as speakers counted down the minutes until early voting in New York state began at 10 a.m. That fervor is a challenge for Representative Mike Lawler and other Republicans defending House districts like this one — affluent and well-educated, where voters overwhelmingly disapprove of President Donald Trump.
In the Trump era, the GOP has lost significant support among White, college-educated voters. Today, Republicans hold only 50 of the 212 House districts where the share of White residents with a four-year degree exceeds the national norm; as recently as 2015, Republicans held 70 of 194 such districts.
