(Erin Schaff | The New York Times) Rep. Steve Scalise (R-La.), joined by other House Republicans, speaks during a news conference outside the room where impeachment investigation interviews are under way, on Capitol Hill in Washington, Oct. 23, 2019. "Republican populists need something more than individual proposals and ad hoc partnerships," writes The New York Times columnist Ross Douthat. "They need to present themselves as a faction, a small alliance within the larger GOP, a caucus with a collective identity for the purposes of proposing policies and negotiating deals."
