All Democrats have to do is to get the "points on the board." Once that happens, any legal cases to expose fraudulent ballots literally takes years.
Unless SCOTUS makes some rulings in the next few months on Trump's election cases in GA, and Kari Lake's in AZ (which is highly unlikely), the same thing will happen to all MAGA candidates in November -- the counting will be slow-walked for a week until the Democrat is in the lead.
The SCOTUS is going to punt and that's the right move.
All of this is politics. So we'll have to go to GA and AZ and change the laws to tighten up election security.
