What makes me curious: I always wondered if the president really has the power people perceive him to have, or if he's still influenced and bound by many people in the background. One can observe this with Obama. He made promises (like closing Guantanamo etc.), which he ultimately couldn't force through. But why? Possibly, because he isn't nearly as free in his decision making. Now, Trump claimed to do a lot of things and I'm wondering if he really can pull that off or if many of his extraordinary claims and goals won't be doable, because of other people with power. This is what I don't like about modern politics: So many things are claimed to be done, but ultimately, it's all bullshit and you only know what you've voted for long after the election – which could be something entirely different than you'd voted for in the first place.
