Perfect storm. If Trump cannot get his Safeguard American Voter Eligibility (SAVE America) Act passed in time, merely a day before voting he declares national emergency - issues executive order, all gun carrying ICE agents instantly transform to voter i.d. agents at every poll station in America. Planned so no time for any court to issue injunction (or other means of delaying 1st level judiciary)? All people without proper valid i.d. don't get to vote, get turned away.
Interfere and you get ARRESTED, paddy wagon on site.
Done Deal.
