Phase 1 will end Obamacare. The Senate rules for reconcilation with a Budget require what is being done to enable ending Obamacare with just 51 votes. Any other technique would allow filibusters and require 60 votes. No Democrat will vote for repeal.

Filibuster is a fake concept and only a rule which can be worked around in a couple ways. We just have to have Republicans that care more about the Republic than they do themselves.
