Two things can stop Trump’s re-election:
Supporting gun control
Supporting the Cheap Labor Express (including H1b)
A possible downturn in the economy or stock market looks unhelpful too.
You are correct.
Supporting H1B isn’t going to do it, and depending on the type of “gun control” that won’t do it either (bump stock ban, case in point - his current approval rating according to Rasmussen is 52%, and we all know it’s probably higher). He’s not going to do anything with regard to “gun control”...it’s all geared to make the Dems come out of the shadows and say more things like Beto...and ultimately, the Dems won’t go for it because it will look like it gives Trump a win....and Trump can say, we’ll, I tried, but I’m not going for anything that infringes on 2A.
