Earlier this year, we showed Trump built a remarkable “plutopopulist” coalition in his campaigns, drawing money from both wealthy elites and an unprecedented surge of small, first-time donors. With Tuesday’s elections, though, that coalition seems to be fraying. What happened? 1/ cup.org/4cfm0Az

A recent @nytimes.com analysis found that over the last three presidential elections "Republicans are overwhelmingly making gains in working-class counties. Democrats are improving almost exclusively in wealthier areas." Our research shows similar patterns among donors. 🧵 cup.org/4cfm0Az

Democrats’ victories may only increase the urgency with which Republicans already view the 2026 midterms, David Graham argues, adding: Trump and his allies will do anything they can to make the election results “closer without having to actually change the policies that they want to pursue.”

People ask a lot about whether protests matter. While Trump’s approval rating is driven by many factors, events like the No Kings rallies likely play a role, too. Media coverage and people seeing their neighbors take a stand help convey that disapproval is not just acceptable but widespread.
