This may be reaching, and may be inappropriate to Politics, but here goes:
Trump "officially" moved from Trump Tower New York to Mar-A-Lago and therefore cast his vote in the Nov 3rd election as a resident of Florida. However, he had previously signed an agreement that he would not use Mar-A-Lago as his residence (as reported here). Not having any alternative address in Florida (presumably), he could not be considered a Florida resident, thus casting a vote in Florida as he did would be a violation of voting rules, wouldn't it? Again, having previously signed an agreement to not use Mar-A-Lago as a place of residence, and having "converted" the complex from a residence to a club would make the complex ineligible to declare as his residence, and thus make it fraudulent to do so on his voter registration, wouldn't it?
