It seems that McCain doesn't mind that the 'Affordable Care Act' (Obamacare) was passed only with Democrats' votes, who wouldn't allow a single Republican to have any say in the least thing about the bill, and McCain will allow it to stay law, because he doesn't want the Republicans to pass a much better bill for the American people, that could be amended by both Democrats and Republicans in the future, once Obamacare is dead, but until Obamacare is dead, most all of the majority of Democrats will not try to pass a better law, only make sure it stays as Obama's legacy, no matter how bad it harms the American people and the US economy.  Why is McCain doing this, it has nothing to do with bipartisanship, or what's better for the American people, but only to get back at and harm President Trump, for doing something that McCain couldn't, win the Presidency, even after McCain supported the political view of "Never Trump" as President.
