I suggest you read the quote again.your quote is about him not being proven wrong, yet ... is pretty damn wrong given the context that the dow the pretty much the rest of the stock market has gone almost straight up since the election.
"He's who we put our hopes and dream with. Now it is easier because we haven't played a game yet," Cuban said on CNBC's "Fast Money Halftime Report." "No reason to rush to judgment or come to any conclusions now. Let's see what happens starting January 21st and we'll go from there. I hope he's a superstar."
And yet, you're the one in need of a breath mint.And now Cuban is kissing Trump's rear.

But as you've said recently, that doesn't really mean anything.
Near as I can figure, he hasn't been proven wrong, at least not yet, and he hasn't changed his mind. He's stating where things are now and, going forward, he hopes Trump will do a good job. What kind of American would not want his president to do a good job...?
