Romney will beat tRump for 2020 GOP nomination
Assuming tRump is not removed from office, he (at 74 years old and still refusing to disclose his income tax returns) would have zero chance of beating out any number of Republicans for the nomination. The primary contender may well be Romney. but it might also be Rubio, Ben Sasse etc.
That would be the best case scenario in 2020 for the GOP...no tRump on the ticket.
