I've been surprised to see so many political commentators both pro- and anti-Trump remark on how "presidential" he looked at the podium next to President Pena Nieto (sorry, I don't know how to do tildes on my keyboard currently). My perception of him was that he looked like he was sulking, like a kid who didn't get his way. Which turned out to be the case -- that he didn't get his way immediately. It boggles my mind that a U.S. citizen would demand that another country pay for something that he wants. Maybe I'm just too diplomatic, but I think it would be wiser for a presidential candidate to ask the Mexican president to increase their border control as well, and maybe even come up with some kind of deal to help them if they're struggling financially. (Deal, being the operative word, here, as Trump likes to think of himself as the master of the deal.) Or, maybe it's not even appropriate for a mere candidate to ask for something like that. We're in uncharted territory.
Beyond all that, what he is suggesting is what Obama has already been doing. Obama has deported more undocumented immigrants than any other president. Including our favorite chef at our local restaurant. Kid did one of his grandma's specialties every Friday evening, and they were all awesome. He was working toward the goal of attending culinary school. He was born in Mexico,. but brought here by his parents as a tiny kid, and so was raised as an American. He was so young when they came here he didn't have a Spanish accent. Tragically, he was deported -- by himself!-- two years ago in his early 20s, to a country he never knew. Maybe I don't know the whole story, but no matter what, this seems incredibly cruel.
