The reason I stipulated that the simple majority in the house should include 1/3 of the president’s party, is that a partisan supermajority could still provide purely partisan articles of impeachment. This happened to Johnson. The house overwhelmingly voted in favor of the articles 147-46.
Only 4 Representatives from Johnson’s own party voted in favor. It was about as partisan as it could be. The Senate also had a supermajority and could have voted to convict, but the constitutional arguments made against impeachment by the defense, which was essentially Dershowitz’s argument, convinced enough Republicans that the rule of law were more important to the Republic than their partisan whims were to them. I’m saying the requirement would be put in place so that impeaching the president does not even make it to the senate unless it has bipartisan support (at least 2/3 of the president’s own party) even if the overall vote is a simple majority.
About the standard of actual damage to the Republic, I’m not sure there’s an objective way to define that. Every side is gonna rationalize it into favoring them. But I don’t really have a problem making that the standard and then watching the parties break limbs while contorting the logic to fit their partisan needs. Doesn’t matter a lot if they still have to get support from the other party.
This would never happen with the dumocraps of today. Their whims are much more important to them than the rule of law.
