Looking at things from afar, whoever is president, they are normally tied up by congress or the senate, get a few things through, but most of their agenda gets stopped.
It makes you think this is just a way of counselling the people, get them to air the problems, blame the other guy, and then after they are elected, said it was the oppositions fault that nothing got done, while it is big business that pulls the strings, that changes laws, and that exploits weaknesses, while everyone else is really believing who is in the white house matters.
I love Trump, because he understands being president is a business advertising opportunity for Trump hotels and golf courses. When a guy can say opposite things about what is happening and what should happen and it does not matter, your realise he is not actually pulling the strings.
Building the wall, what a joke, had to squeeze billions out of the government to even get something done. It was I will get Mexico to pay. If he had said I will build a bit more of the border fence as a wall, and then nothing much will change, would people say, "Yea, he is a real mover and shaker"
Even Obama could not close Quantanomo Bay, failed on Obama care, so you have to ask, what did he do? He got Osama, or rather a dedicated operative chased him down, and Obama pulled the trigger.
Leaders matter as influencers, but as clowns you just got to laugh.
