Actually, what Congress should do is work on improving the foundation of Obamacare. One party has ignored that request for over seven years. Not sure what you've been reading, so far be it for me to comment on it. I think if you search the NYT you'd find some positive things stated about Obamacare, the WJR's orgasmic hots for the private market leads me to believe that it wouldn't have as many positive things to say about Obamacare.
Decline of the Democratic Party? Even while running the worst candidate imaginable amidst the "rumors" of election interference against them, they garnered 3 million more votes. I'm a strong believer in the pendulum theory of politics, that things will swing back whenever there's a tilt one way or the other.
Now here's the thing, these message board debates always generate more heat than light. A series of multiple 3 or 4 paragraph exchanges never sways an entrenched position. The format is too constricted. Also, if I wanted to engage more in this type of discussion I'd abandon my nice comfy work as a copy editor at home and return to the health care company where I was formerly employed. Unless prompted by a snarky attack that begs a retort, I'm out of this dialogue.
