Mark Cuban, 61, is supporting Kanye West‘s potential presidential run — sort-of. “If there was Rank Choice voting available and @kanyewest was on the ballot with @JoeBiden and @realDonaldTrump, I would have @kanyewest ahead of @realDonaldTrump,” the billionaire tweeted on Saturday, July 4, effectively saying Donald Trump, 73, would be his last choice out of the three.
