I have to admit that all the stuff I read in various places about it being in 2022 or 2024 makes me very nervous. There won't be a country to be President OF if he waits until 2024.
On the other hand, he's made several statements alluding to a time earlier than 2024. So I think I'll go with those. :-)
It’s hard to put a time on when he comes back. Although I just heard that 30 governors are meeting with Trump and Pompeo now so that’s encouraging. Only one thing they could be meeting about, IMHO.
