Senate Majority Leader Mitch McConnell, R-Ky., on Thursday conceded the Republican Party faces severe challenges in 2020, but he asserted that making the next election a referendum on socialism could preserve GOP control of the Senate and reelect President Trump.

McConnell, 77 and running for a seventh term in Kentucky, said Republicans need to heed warning signs from the midterm elections, a blowout in the suburbs that cost the party control of the House of Representatives plus Senate seats in Arizona and Nevada.
