Certainly fixing the ACA is the most efficient, least disruptive, less expensive and most rational choice.  Your insistence that "it can not be done using Obamacare as the starting point" is just extreme political partisanship, not based on truth or principle or what is best for our country and Coloradans. It is this (and your) attitude that has gotten us to this extreme point of constriction - not because of Democrats or Independents.  The best thing is to  improve what we have and shore up and infuse confidence in the insurance markets so they can function  but that would require that the GOP stops wallowing in the swamp and learns to work across the aisle with Democrats.  At least some GOP Senators are now saying this.
