Hard disagree. The metric ought to be whether they'll make it out of the court case clean or not - just having the ability to check power in a meaningful fashion when it goes off the rails is something you're only afraid of if you're a war criminal or other flavor of Massive Piece Of Shit.

The reason the rules are the way they are is pretty obvious; we haven't had a not war criminal in office possibly ever, definitely not in my lifetime. It's time we faced the facts - we're the baddies.
