Intelligence and good judgment?

This is the man who accused a police officer of racial violence against a professor before finding out any of the facts. He turned out to be very wrong.
This is the man who sided with a violent youth rather than the citizen being attacked, even wishing the youth were his own son. Again, he was very wrong.

If you can call that "intelligence and good judgment" you are certifiably insane.

"At least in terms of his public persona, he is the only US president I ever feel like reminds me of my friends and colleagues"

That is because you choose to allow your nostalgia and emotions to blind you to the reality of just how corrupt and utterly contemptible this man is.

"At the same time, he's dispelled my hope that a president alone can change the fundamental problems in the gov't."

I'd seriously suggest you go back and read the Constitution. It is not the President's job to set policy. That was started by Woodrow Wilson back in the early 20th Century. Policies are laws and laws are the realm of Congress and the Legislative Branch - not the Executive Branch.

Sure I guess so, I mean ethnic tensions have grown to heights not seen since the 60's, our privacy has been Violated to an extent never previously seen, life expectancy in the US has actually gone backwards, insurance rates has gone in the opposite direction of quality of care, new regulations and the threats of new regulation has left industries baffled and shuttered to extent unseen since the Bolshevik revolution, Iran is laughing while using our tax dollars to support terror but sure he golf's so he must be a good guy...right?

Yes, completely brainwashed.
