Republicans lost control of the House in 2018 and now could lose the Senate this year. Their fortunes seem tied to Trump and his agenda, but new research suggests they would be better off trying to distinguish themselves from him and his policies. Sarah Treul finds that votes to repeal Obamacare cost Republicans seats in Congress in 2018. They did not listen to their constituents at Town Hall meetings and the repeal effort resulted in lower vote share. Andrew Ballard finds that Trump endorsed a lot of Members of Congress in 2018 but it actually hurt those endorsees, stimulating the opposition more than the supporters.
