Yes, this was a good victory for the country. I'm especially appreciative of the people who put so much pressure on their representatives and senators in town  halls, letters, calls, etc. This is grassroots democracy at its best. Going forward, vigilance is the word.
Trump and Ryan are lying when they say that the ACA is imploding under its own weight. The CBO has affirmed that that simply is not true. If the ACA fails, it will not be because it imploded, but rather because Trump and his co-conspirators explode it. Trump's Executive Order to federal agencies instructing them not to enforce the ACA mandate is intended to undermine the ACA. 
Trump bragged about profiting from the collapse of the housing market. Make no mistake about it: he will delight in the collapse of healthcare for millions of people if he sees some benefit -- any benefit -- accruing to Donald J. Trump. Surely no-one believes any longer -- if they ever did -- that he cares about healthcare or knows anything about it.
