Yes, I would also want a President faithful to the Constitution. That's why in the primaries I voted for Ted Cruz. He didn't win. So now my choice, knowing that only a Republican or a Democrat will win, my choice is between Trump or Biden. Between the two, Trump has shown his governing politics to be far more faithful to the Constitution than Biden's long history of becoming more and more Progressive and whose present position will be dictated by the Democrat Party which has actually become the Progressive Party trending heavily toward socialism and is being supported by the Communist Party and leftist organizations and movements.
I have no doubt, absolutely none, that the Progressive party, given enough power and a little more time, will gut the Constitution with novel interpretations making it absolutely moot, totally irrelevant, and finish replacing it with it's dream of some form of an unhampered Administrative State--or maybe with a whole new Constitution, or none at all.
If you don't know what the American version of the "administrative state" is, and what is the Progressive project of making it our functioning form of government while rejecting the Constitution, the following two articles give a clear picture.
The first,

The second and more interesting one details the Progressive project of rejecting the Constitution and basically replacing its functional powers with a centralized administrative government:

I think Pete F and Spence, if they read the articles, will agree with the notion of an administrative state, and prefer it over the Constitution and its separation of powers doctrine.
