A breakthrough on the long-stalled effort to repeal and replace Obamacare could be around the corner. Of course, that's if President Trump's White House and Congress can stop butting heads.

White House Budget Director Mick Mulvaney told Fox News that a vote on healthcare could come as early as Saturday. But two members of Congress seemed genuinely puzzled about that time frame, telling the Washington Examiner independently that a Thursday vote is the goal.

"[Reps. Fred] Upton and Bill Long have moved to 'yes,'" one member said referring to two key centrists who previously opposed the reform. "My understanding is that tomorrow is still the goal."

Since coming to power, Republicans have only talked about repealing and replacing Obamacare. Two votes on the bill were canceled at the last moment. Conservative opposition from the Freedom Caucus sunk the first bill and complaints from the centrist Tuesday Group has doomed the second draft so far.

That's what makes Mulvaney's statement so puzzling. Now that Speaker of the House Paul Ryan, R-Wis., has all his ducks in a row, it appears that the White House is monkeying with the schedule.

"I'm hearing tomorrow," another equally perplexed Republican explained. "A well-paced Republican told me this morning that they're three votes away."

At best, those cross-cutting narratives reflect confusion. At worst, as CNN's Phil Mattingly noted, it makes it seem that the White House is intentionally trying to undercut Ryan.

If Republicans are finally going to put the nails in the coffin of Obamacare, they should at least try getting on the same schedule.
