As many already pointed out, Trump run on the campaign to explicitly act differently than Obama. When you bring up "but Obama did the same", while I disagree your comparison is valid, you at the very least must concede that Trump is breaking his campaign promises. Do you agree to that much?
I guess Trump is more of a politician than people give him credit.
But what is your complaint about him, then, if he does the same things as do other politicians? You hold no one else to the same standard you hold Trump. Doesn't that make you a hypocrite?
When people start complaining about Obama (and others) for doing the exact same things as Trump, maybe I'll start taking them seriously.
If you look at the major policy shifts that have taken place since Trump was inaugurated, where it counts, he has performed entirely different, and I would say better than Obama.
Performance and policy are what matters.
