Hindsight is 20/20. We place our hopes on leaders who we want to believe will deliver what they promise. In our form of democracy, the most well-intended leaders cannot deliver. They don't have the power of a dictator. I don't recall who said it, but the quote is: "The best government would be with a benevolent dictator.".
From the very beginning of Obama's election, the GOP vowed to make him fail. How many of us would continue to work knowing that whatever we propose would be blocked? ACA was something needed and if the only thing he accomplished while in office was to give people affordable healthcare, he succeeded. One cannot appreciate the value of healthcare until they need it.
As for immigration reform, that problem seems to carry forward from one Administration to another. Former Presidents used Executive Orders for a temporary fix, but it was not a long-term solution. From what I read and hear, that is still the problem.
Sometimes I just want to keep my mouth shut and not say anything. Afterall, I am not personally affected and it is not my problem. I cannot live with that attitude. I realize that "There, but for the Grace of God, go I." Those who care, speak out. Those who don't care, usually say nothing - at least nothing constructive.
My views are not the norm. My sympathies are with the oppressed. I usually side with the underdog. It's just who I am. The more someone beats up on a person, the more I am inclined to take up for that person.
