Politicians lie all the time. It goes with the territory. It just depends on the nature and the significance of the lie. Sometimes it's not always making a false statement or one not supported by the facts. Sometimes, it's a matter of presentation and how someone tells something. Sometimes it's a matter of presenting a false image to the public or propagating myths (such as the "American Dream").
Any politician that does not say that Wall Street is evil, that the bankers are evil, and does not rile up the public against them and other institutions which have been screwing the American people for so long is the worst kind of liar to ever pervade politics. Trump didn't say that, neither did Obama, and neither did Hillary. That makes them all the same.
If Obama was so great, then why didn't he lock up the insurance executives, the corporate CEO's, the bankers, the real estate moguls, and all of the rest of those scumbags? If he really cared about America, he would have. Why didn't he do that? Trump isn't doing that either, although at least he's giving something back to the American people by opposing free trade (something else Obama and Clinton refused to do). It's still the lesser of two evils, but there's no greater evil than a sell-out.
All you can focus on is minutia, while I'm looking at the bigger picture.
