I don't think it's possible to predict this, even with a fully stable and rational White House. It's often impossible to know how things can or will backfire.

If that's actually beneficial to Trump then none of this matters, because the Republicans can just shut it down themselves no matter what the democrats want or do.

Meanwhile, what power might this give him that he hasn't already seized without resistance from Congress? He's taken spending power and partially claimed taxation power already. He's been illegally firing people his entire term so far, often en masse. So what's the "more power"?
