Actually letting the issue go will be best for everyone. Dems and liberal independants created it when they had a three fifths supermajority in the Senate before Scott Brown was elected to fill Ted Kennedy's seat, something that the Republicans haven't had since Reconstruction. To fix the mess created by one party rule will take both parties working in good faith and that will only happen in an emergency setting.
I believe next year the "Cadillac Tax" kicks in on health plans and the Risk Corridors (Insurance company slush funds) are empty, so union working folks and insurance companies won't be contributing money to politicians in 2018 who don't get busy. If insurers lose more money this year and even more companies pull out of the exchanges, Ol'bamadidn'tcare repeals itself. You can't buy insurance without insurers in the market.
