The truth is that you're going to have to:

1. Raise good kids
2. Form your own party and run for office
3. Make a lot of money and fund media organizations
4. Make even more money, and control tech organizations
5. Realize that's never going to work out, and setup a right-wing Chaz somewhere with defensible terrain. Probably attached to a decent foreign state. Assuming the US does not exist at that time, which it probably will not, that basically means Russia.

Good luck!
