This is the simplest thing in the world to solve: If Trump, currently a Florida resident, decides to choose someone else who is a Florida resident to be his Veep, then one of the two of them need to move from Floria. At a minimum, they can’t both be residents on the day on which the Electoral College votes; however, the much safer course of action would be for that person to establish residency in another state prior to the nominating convention, and to maintain that status until the inauguration.
As mentioned in the article, Cheney re-established his Wyoming residency a couple of days before the 2000 convention. Trump has a home in NYC (though one could certainly understand why he wouldn’t want to further expose himself there) and has a luxury golf resort in Bedminster, NJ where he could also establish residency. However, both of those are hostile jurisdictions, so he’d be better off buying or leasing a place in Texas, which has no income tax and is almost certainly not going to start up any lawsuits or prosecutions against him (nor try to take away his guns or right to carry).
Alternatively, of course, the Veep candidate could also establish residency elsewhere quite easily - but both Rubio and DeSantis may have political/legal reasons to remain FL residents until they official quit their present job on 1/20/25. They also have less financial resources with which to do this than Trump.
I do think people are at the point accept that 2017-2021 was a much better time in America.
