We don't want our President rendered entirely ineffective by state charges and lawsuits. We need him to be able to do his job free of state legal obligations.
This is why our system removes the President first Then he can spend the rest of his days in state and federal court. But while his job is the Presidency, he has other things to do.
It doesn't matter whom the President is. This is the system we installed and for good reason.
The system is poor, and outdated. There was no testing of it before-hand, there hasn't been significant exercising of it, and in retrospect its weak and absurd.
- POTUS can't be effectively investigated by Congress, they have no teeth if the DOJ doesn't play ball. Even DOJ has extrem limits on investigating POTUS as we saw with SC. Congress has a tiny fraction of that authority.
- The jury of the Senate, is biased, witness-tampered, is tied to their career/legacy/employment/reputation in terms of how they vote, and is stacked in favor of one party or another. "justice" is a complete crap-shoot with such a design.
- POTUS also has unlimited pardon power, and is able to effectively let anyone take the fall, obstruct, etc., with only a "legacy" impact, no fear of punishment like in every other case.
The idea that removing a president is somehow a reasonable remedy to the inability to try them for crimes, is absurd, sorry. If you have BOTH houses vs the opposing party, you have a shot. Short of that, it's simply not an actual option unless it was something like they stripped off their clothes and went on a shooting spree.
Crimes don't even toll while in office. If the statute of limitations expired, nothing DOJ can do after the fact, regardless of impeachment.
So many holes, it's basically a fail-safe that only triggers in the most calamitous, or partisan, of circumstances.
Not saying they could have done better at the time, you get what you get. But look at our system of laws...that get tested all day every day. They have evolved millions of times, been shaped and corrected, tweaked and re-tweaked as we've found issues.
Impeachment is very rarely used, only for a handful of people in the nation, and elections are apparently seen as the catch-all to make up for that poor system anyway.
