In the war of progressive vs. conservative (a euphemism for American), moderate Republicans are on the side of progressives. They are just a faction within the progressive movement. That is why they fight so hard against conservatives. They are not on our side. They will dicker and bicker with more left-wing progressives. But they accept progressivism, and that is why nothing ever gets rolled back, it only moves further and further towards total control.
