Remember how Democrats held America hostage after Medicare Part D passed? Remember how Democrats pushed the country toward financial Default over the Bush Tax Cuts? Remember how they shut down the government over the Iraq War?
No, you don't; because it never happened. In fact, Democrats helped implement these programs they hated, because they passed in the legal way the Constitution requires.
The Affordable Care Act (or "Obamacare") passed the House, passed the Senate, and was signed by the President. And just for good measure, the Supreme Court gave it an "OK" as well. And then Obama went and won a second term against a guy who promised to dismantle Obamacare.
But the Republicans, who claim to love the Constitution, say that none of that counts.
Tell me again that there's no difference between the two Parties. Tell me again how "both sides do it."
