The whole reason is to keep Trump tied up in court in several different places simultaneously, New York, DC, Miami and Atlanta.
So he won’t have time to campaign for POTUS. That’s all this is about.

How much does Trump really need to campaign? Most people who are not going to vote for him will never vote for him regardless of what he says or does. Same goes for those who will vote for him, even if they have to write him in.
