I'm not sure it's as simple as that...
Without the employee mandates Obamacare is dead...or we are on the hook for subsidies forever...
The GOP will have to come up with a plan to get the former Obamacare clients covered with same type of plan...
I have always thought the feds needs to give the states one year to come up with their own plans to get everybody in their state covered...each state has their own unique issues and can best figure out the most cost effective way to do it...
I'm sure in every case it will be cheaper than Obamacare...
Local control would be ideal. However, the simplest approach would be to just expand Medicaid (which seems to be the largest effect of Obamacare anyway) without all of the mandates - I'm not a fan of the program for many reasons, but it would have been far less disruptive than Obamacare has been.
