How about this one. Trump, a previously lifelong Democrat decides to try for the Democratic nomination as well as the Republican nomination and then runs under both parties?
If, in the next few months, President Trump rescues the economy and puts an end to the Corona virus then Both parties will happily re-elect him in November. Congress might then amend the constitution and make him president for life. Ivanka will be designated his heir and a Golden Throne will replace that desk built from an old boat.
