This is kind of what this whole Trump for President campaign is about. I don't think the guy has a clue how to run the country and I don't think he thinks it's even necessary to prove that he does or to explain what he would do other than to say, "I'll handle it." I also don't think voters are ever going to let him get close to having to deliver on any of his brags.
But he's really good at making the election be all about him. I wouldn't get a bulletin like that if Rick Santorum was speaking at the border. Maybe if he was crossing it as part of leaving the country forever…but not speaking there.
