It is in the character of 'Crats, when weighing the alternatives of acting with rational motive or vindictiveness to go with spite, not reason. Long-term they may well regret this decision because it could cost them dearly with a significant number of voters. 

I will also make a prediction - Xiden will declare his candidacy either immediately or just after the moronic, treasonous arraignment. He'll want to ride the wave of inevitable euphoria that will sweep through the  ACF True Believers. He (which is to say his handlers) know that he's unpopular, so this will be a way to steamroll over 'Crat detractors. It also makes sense politically because that way if he loses in '24, he can blame it on the "interference" of Bragg's investigation. 'Crats ALWAYS look for a way to be victims.  

I've given up making long-term prognostications about who will win, because I am a graduate of the EIB Institute of Advanced Conservative Studies and we are taught that the issues which usually are key to deciding elections do not emerge until well into the cycle.
