After their defeat in the Supreme Court, foes of the Affordable Care Act plan to chip away at the law by actions in Congress and state legislatures. Still,  some opponents, such as the liberatarian Cato Institute, vow to  keeping trying to overturn the whole law.

But as “Obamacare” becomes more entrenched as millions of people become dependent on it, getting any major changes will become more difficult. For years after the introduction of Social Security, Medicare and Medicaid there were Republican-led campaigns to eliminate those laws but the millions who benefited from them eventually made the demise of these laws politically impossible.

Remember how strongly Tea Party folks opposed any limits on their Medicare benefits?
