It is true, as you write, that obamacare was "passed by a majority of Congress," but you fail to note that the "majority" consisted entirely of Democrats (i.e., the party of slavery and subjugation).
That noted, thank you for your well-presented perspective.
Speaking of reason and majoritarianism, one of Mark Levin's favorite authors, Randy Barnett, recently published a terrific new book: Our Republican Constitution. I'm reading it now. Among other topics, he explains the warped Leftist approach to our Constitution and why originalism is the only sensible approach to securing freedom.
