here are two thoughts I own.
1) Obamacare is going to cost much more than projected and have many unanticipated, mostly bad, consequences.
2) That said, where in the world are you getting this line: "removing meaningful choice and increasing costs for twenty-five million people"? Some costs are going up, some are going down, and millions of people now have a choice to get health insurance (and outside of NC, a choice of several different plans and providers) where before they had one choice - be uninsured and go to the ER for everything. This line is just as much of an oversimplification and head-in-the-sand refusal to admit reality as the Obamabot failure to admit that the "you can keep it" promise was broken.
Here is a relatively "fair and balanced" article on the subject.
