Different animals.
One is comparing something that has passed and is being implemented (PPACA) with Medicare for All. The other is lack of votes on anything of substance.
Yes, I was too curt - of course one should agitate for things one wants a vote on.
But if you're willing to throw out a flawed but decent piece of legislation for something that would be better in many respects but does not have the votes, well, you'll get neither. And if you're expecting Congress to throw an entire industry (health insurance) on the unemployment line at one fell swoop, at a time of high unemployment, well you're dreaming. And not in a good way.
Cheers,
Scott.
