Vox has a good condensed version of the bill, which has next to nothing to do with health care. In a nutshell, people will spend more for less, and redistribution of wealth will return to the American trickle-up norm. Old people and chronically ill people will be harmed most. It is mean-spirited legislation that seems to have no goal but to reverse all that our First Black President tried to accomplish.
Meanwhile, some GOP senators are already out opposing it because it is too "liberal," by which I think they mean it costs too much and doesn't lower premiums, which is certainly true. So expect amendments, some of which may make matters worse.
