48. And if that's your case, then I can only say:

Lack of foundation, counselor.

One can go by the lessons or history in THIS country, or one can imagine all sorts of fiction based on what's happened elsewhere... I prefer facts in evidence, and given I lived through Watergate, it seems somewhat more on point than the Ides of March, much less what's happened in a bunch of developing countries with no significant tradition of democratic self-governance.

As far as Nixon goes, his approval ratings were at 48 percent the month before the hearings began; Trump's are at 38 percent today, without the results of the Mueller investigation or the mid-terms, much less serious hearings. As far as your questions go:

1) SCOTUS. Yes, the Court will enforce a subpeona, even with Kavanaugh. None of them will go down with Trump's ship, from simple self-interest, if nothing else.
2) Will Congress enfore? Yes, same reason as above.
3) If the House impeaches, will the Senate move to remove him? Yes. Self-interest trumps all.
4) If Trump orders his followers to commit violence, they will laugh at him and change the channel. These yahoos are not the SS; hell, they're not even the Klan. On their "best" worst day, they are the Branch Davidians, maybe the Order or SLA. Any that cross the line will be met with deadly force, and they will die quickly.
5) Will Republicans hold him to account? Yes, for the same reason Goldwater, Rhodes et al told Nixon to scram.
6) Will any Democrat be in a position to do so? Yes.

Here's some evidence; perhaps you should consider it:
