Republicans have reached a gut check moment: After spending more than six years vowing to fix the flagging patient that is Obamacare, it's the GOP's own repeal effort that's on life support.

Undoing the health care law despised by conservatives seemed to be a straightforward proposition for the party after it won the White House and retained control of both chambers of Congress. Instead, Republicans are sniping over how much of the law to scrap, what to replace it with and when. At this moment, it's far from a sure thing any plan could get through Congress.

Consider Paul Ryan's feel-good meeting with Senate Republicans on Tuesday. The House speaker trekked across the Capitol to reassure senators that lawmakers are making more progress toward repealing the health care law than the media are reporting.
