I think 2018 will tell the story. If the the GOPe picks up seats in the midterm then I think the dims are in real profound trouble. At that point it will be true panic time and I assume that’s when they will go the domestic terror route if they haven’t started already.
On more thing I think the Republican Party is on death watch as well unless it adopts President Trump’s pro American agenda.
The Democrat party is already in profound trouble. They've been in steep decline since 2010, when they began losing races at an accelerated rate. Over a thousand Democrat seats have been lost to the Republicans since then, and the Dems now find themselves at their lowest point of power since the 1920s. One hundred years of electoral gains on their side were wiped out during the Obama years.
If they weren't afflicted with such a severe case of Reality Defiance Disorder, they would have already tacked toward the center to stop the bleeding, but the sickness is just too strong. I fully expect them to continue doubling down on the alien leftist politics that got them where they are today. They'll go down to even worse defeat, screaming, "Obama Ackbar!!"
