If the Republican "health care" bill fails in the House, as now seems likely, it will be a big deal for three reasons:
First, it will stop the Republicans from doing a great deal of harm to a great many people. That really matters.
Second, it will make it more difficult for the Republicans to advance other legislation on their wish list, including an enormous tax cut for the rich.
Third, it will markedly diminish Trump's political clout at the very beginning of his presidency.
This opens the way for progressives to nominate strong leftist candidates for the House and local offices. It even creates an opening for a new discussion of a single-payer system, which looked dead not too long ago.
I honestly did not see this coming. We must take such victories as we can wherever we can find them.
