I wrote, “But if that were the only remedy, then a rogue president plus 34 partisan hacks in the Senate could do anything.”
You answered, “Isn’t that what we have today?”
That’s what we have IF the Supreme Court agrees that a president can’t be prosecuted for anything unless there’s been an impeachment and a conviction. On that view, Biden can leave office on January 20 and never face any criminal liability for any of the charges you went on to list.
My view: Biden can’t be prosecuted for bad decisions on border policy, because, no matter how bad the decisions were, they’re part of his official duties, so he’s immune. But if it could be shown that he took bribes or the like, then he could be prosecuted. That will be the result if (but only if!) the Supreme Court rejects the argument you make in the OP.
Your argument is situational. That we should carve out exceptions and go outside the proper Constitutional remedy because, oh dear, this or that crime is so heinous. My point is, unless Biden is impeached and removed from office, he will walk away scot-free and never be held accountable, regardless of how much treason he committed, how much bribery he engaged in, nor how much of any lawless activity he engaged in WHILE IN OFFICE.
What’s being done to Trump, to wit, the grotesque subversion of the weaponized legal system to take out the leading opponent of the regime, is yet one more example of wisdom of our Founding Fathers. What they’re doing to Trump is what happens when presidents are stripped of presidential immunity.
