I understand your fear — and that of many others who have pre-existing conditions. Please try to relax. This is going to be a long battle through the courts. And I do not see any way for our government to do away with required coverage for those who have pre-existing conditions. Obamacare goes forward for 2019. There will be a big fight in the new Congress to replace it. And you can be sure that pre-existing condition requirements will be part of whatever replaces it, if the court eventually strikes it down.
This is pure politics, not common sense. I think America will rise up in unison because this is a problem that affects both wealthy and poor!
