He's got to do a reality show first. Even better if the theme has something to do with "the lefty nerds at the company he founded don't want him around anymore, so what's our good buddy Mark going to do with all that extra time? You guessed it: custom 4x4 trucks!"

Zuck's Customs would be great. Definitely he wanted the President thing before, but a after seeing the last 3 years, does he really still?

BTW, don't we need to have a woman president before the next white dude anyway?

If that's the case 2028 is the earliest...
