Here's the totality of the "sabotage":
They will blame the next round of premium spikes on the GOP because Republicans repealed the individual mandate, eliminated a low-income subsidy, and let people enroll in health plans that don’t have the full range of ACA benefits and patient protections.First of all, the low-income subsidy was ruled unconstitutional by a federal judge, so this argument is that Trump adhered to the law and ceased illegal funding.
Second, when it comes to the individual mandate, the "young invincibles" were already choosing to pay the tax penalty over expensive coverage. Repealing the individual mandate only recognized the fact that the young'uns couldn't be coerced into buying something that was a terrible deal.
The final sabotage is giving Americans the freedom to purchase insurance plans that align with their individual needs instead of ones larded up with options they don't want.
So there you have it: Republicans gave you the freedom to purchase health insurance options you want - or none at all - and ended illegal subsidies. Good luck running on ignoring the law and forcing Americans to buy something they don't want.
