I watched some of that video, never seen Trump b4. In fact I still haven't seen a speech by any other pres candidate - shows how much I care about national politics. Anyway, I like what he says, for the most part. Only exception, he wants to "take out" ISIS - I don't, in fact I rather approve of ISIS. And, the most important issue facing US is wealth inequality, which Trump doesn't mention - seems he's in favor of it, actually. His main message is, US is behaving stupidly, giving away money, jobs, benefits to everyone - illegal immigrants, China, etc. We need a "tough negotiator" in the White House. Makes sense.
the question what he would actually do if president is somewhat irrelevant. The pres doesn't have the powers that he imagines. Talks about "charging Mexico $100,000 for every illegal", and "charging Ford 35% tariff for every part made in Mexico" - pres can't unilaterally do such things, need Congress etc. Meanwhile any federal judge can negate anything the pres does in 5 minutes - call it unconstitutional. So he seems to have a lot to learn about pres powers.
Perhaps he wouldn't even try, just start stealing as much money as he can. Who knows, who cares? The race is not about substance, rather it's about the message. If any candidate says the things I want to hear (#1, take back the money stolen by hedge fund managers) - I'll vote for him/her even if I know certainly they're lying. If elected it would show what the American sheeple actually want - it's publicity for the cause. If the person elected actually does (rather, tries to do) what they say, that's great. But even if not, the message still got out there.
Notwithstanding Trump, Alfred E. Neumann is still my preferred candidate; unfortunately according to the polls he doesn't have a chance.
