He tried to force the democrats to help fund his "AntiMexican Wall" with the threat of a Government Shutdown, Pelosi & Schumer didn't fall for it, and predictably Trump folded.
Kudos for the democrats for hanging together in face of adversity, we could all use more of that I am sure. Otherwise this yet another historic lesson, Congress can Blackmail a US President if that body is sufficiently determined or the issue is important enough, but it remains difficult for a sitting US President to do likewise and the same to Congress...even the so called much buffetted minority party.
Trump doesn't get that, because he has almost no discernable political skills and he isn't gonna develop any either if I am any judge.
No, he'll retaliate by ramping up enforcement in cities and localities, more round ups, more punishment of those what can't fight back, more mayhem and maybe a nice tasty stand off with a sanctuary city. In that way, he will build his wall and it'll be a nasty one, look for it.
