Even amid a unified GOP government, Trump will have to face intra-party detractors when he begins his second term in January.

Republicans have won enough seats to control the U.S. House, completing the party’s sweep into power and securing their hold on U.S. government alongside President-elect Donald Trump.

President-elect Trump now has a clear path to enact his agenda and fill out his administration with both the House and Senate in Republican hands come January.

Inside the GOP, meanwhile, Trump’s reelection after one term out of office has cemented the ascension of the populists, who have leapfrogged traditional conservatives and now command the party’s governing coalition.
