Trump's Democratic deal for three months of debt ceiling relief hit congressional Republicans like a bucket of bat urine.
There was an almost feral recoiling within the ranks.
With that deal, Trump ensured the Democrats could still campaign on the debt ceiling in 2018, and left them in a stronger negotiating position for future legislation.
More importantly, Trump removed the debt ceiling hostage from the room, infuriating the hard-right Freedom Caucus and the Republican Study Group, whose members wanted in the aftermath of their ACA repeal failure to use the ceiling as leverage to attack Medicaid again.
Finally, just for flavor, he made Paul Ryan and Mitch McConnell look like a couple of windbag backbenchers who have no idea what's really going on because they never get invited to the real meetings.
