Unsealing indictment, and arrests, a month before the November election, would be utterly retarded, and would make sense only to some boomer politico with glory days in the 80s.
Good strategy for 1988. Fucking dumb for 2018.
First many people vote weeks out, in some places a month out, nowadays. If your big news percolates up through the news cycle beginning a month out, you WILL lose a SHITLOAD of voters you might have gotten, or gotten to stay home.
Second, political decisions are made much earlier based on completely different info than in 198i. People don't wake up and read the paper to learn about politics. They get it drilled into them day in and day out on social media and by home visits from contacts arranged through database marketing. Your new friends are telling you about the political news. The "news" orgs aren't.
Arrest Democrats a month out from The election and many voters won't know what it means until AFTER they vote, because all they will get will be a filtered version and their voting decision will be cemented by propaganda.
Surely Kushner knows this shit. Hopefully he or someone younger than 60 will step in to assist.
