No, I would not vote for Cuban. He is a social liberal, he supported Hillary. President Trump would beat Cuban easily. Mark should stick with Shark Tank and the Mavericks.
I would vote for almost anyone other than Trump. I don't think the social experiment of having a "businessman" as president is a success - at least not with this particular businessman. It would have to be someone who understands how the three branches of government work, how laws are enacted and someone who is more interested in the welfare of the country than his own welfare.
Trump supporters KNOW he is a consistently heartless lying selfish SOB despite their impassioned denials. That is what they PREFER Spunky. What can you do? SIGH. Thank you for your reply and Happy Tuesday. As they say the heart knows what it wants. :(
