Senate Majority Leader Mitch McConnell said Thursday the Senate is unlikely to pursue a repeal and replacement of Obamacare next year, bowing to the reality of a narrower Republican majority in 2018.

McConnell said on NPR on Thursday that the Senate was unable to repeal and replace Obamacare with a 52-48 majority earlier this year, and indicated it will be even tougher with one less Republican. Democrat Doug Jones won an upset victory against Republican Roy Moore in Alabama this month, narrowing the GOP margin even more in the upper chamber.
