Not a surprise – he’s been threatening to do this for months. I always suspected that the GOP strategy for repealing Obamacare might be to chisel away at it with little acts like this and let it fail on its own, like putting a plant in the sun and purposely not watering it, then claiming the plant wasn’t a hardy variety because it died.
Millions of people will suffer, perhaps die earlier, if they lose these subsidies – because they will simply drop their insurance. Millions more (including me) can look forward to higher premiums due to fewer people in the insurance pools – or even more insurance companies pulling out of what looks like a sinking ship.
Elections do have consequences. I would say the same thing to the Bernie Bros that you have: they only cared about their own feelings, not about the real-life plight of millions of more vulnerable Americans – though I don’t blame them entirely for Hillary’s loss. They certainly helped her lose, e.g. in Pennsylvania.
