Umm simple, by filing motion, after motion, after motion to protract the proceedings, stall for time and run out the clock to election.
In the document case all of that was entertained by a Trumptard named Cannon, who stalled, and stalled and stalled, until one day when all the stalling ran out she threw out the case because supposedly Smith was TOO independant from DOJ - a conclusion she could have arrived on DAY 1 of the case. Of course if she did that, then the case would be refiled in another court and Trump would 100% get a verdict before election.
Anyone familiar with the proceedings knows that.
