MARK CUBAN: Donald has done a great job of setting the agenda for the media. The guy is a master at headline porn. You just want to deal with the headlines and not look what's underneath it, and there's nobody better at it than him. But that's not the decision-making -- that's not what I look for when it comes to deciding who I want to vote for for president. At some point, somebody has to govern. At some point, he would have to understand policy. At some point, he would have to get into details, and he just has not shown a talent for doing any of those things.
