No one could have possibly seen this coming (boldface mine):

Mitch McConnell is taking the reins of an immigration debate that may prompt a fix for “Dreamers” — or quickly spiral out of control…

But McConnell does want strong GOP backing for any final bill and will be loath to pass anything that can’t get at least 30 Senate Republicans in support, according to two Republican senators. That might go a long way toward insulating his party from conservative criticism, as well as winning over President Donald Trump and House Republicans…

Democrats, meanwhile, have grown increasingly impatient with McConnell, who only promised an immigration debate as part of an effort to get out of last month’s government shutdown.

Since Democrats didn’t call Republicans’ bluff, Republicans now know that they can get away with anything. McConnell will come up with some bullshit rule or problem, and tank the deal, sure as shit.

Once again, professional Democrats’ aversion to wielding power comes to the fore…
