What is happening to Trump now is a test case. With the buzzards circling above, they will do everything they can to get this over the line. If they manage to punish him enough, more charges will follow. But if he walks away from court still able to launch a leadership campaign, they will probably have to wait. No point chasing it now if he might well shrug them off. My bet is that they will leave it until the next elections. Not just to discredit him further, but to interfere with his campaign.
