A lot of politics is purely performative. I’d wager over 50% of presidential candidates in any given election know full well they have no chance of securing the nomination but run anyway to build up their profile for a cabinet position or a future run.

Making a noise today about impeachment would be similar. It would play into a strategy for winning the midterms. It’d generate more headlines about the blatant illegality occurring under our noses, it’d be a stick to beat rivals with come election season. No, there would be no hope of it actually resulting in an impeachment, but that would be beside the point.
