Obamacare was made law back in the Zer0’s first term. It merely went into effect this month. So in a way, the “referendum” claim is correct, since each election since it became law was a chance to reverse it by putting politicians who were against it into office.
However, you are correct in the reasoning behind why they set it up to only come into effect after Zer0’s (potential at the time) second term.
You're contradicting yourself. How could there have been a referendum on something that didn't "come into effect" until after Ubama's re-election? All there was was a law that the ignorant chattering class knew nothing about. Like Pelosi said, it had to be passed to find out what's in it. And the people are only NOW finding out "what's in it".
