The court cases against Trump were mainly to fuel the 14th Amendment question on whether or not they can remove Trump from the ballot.
Sure, they'd like to hurt him financially, and actually throw his ass in jail for a while, but no one with an objective legal perspective actually expects any of these to hold up on appeal.
Since most of the 14th amendment cases are crumbling, their fall back position is to try to yet again discredit Trump in the minds of the MAGA voters. This didn't work for Russia, Russia or Ukraine, Ukraine, but they have no other card to play other than ramp up an even bigger voter fraud machine than they needed in 2020.
They put Trump in jail and he becomes even more popular in the minds of conservatives - - Trump won't quit even if he has to serve time.
