As many times as he said he doesn't support it, he also said he does support it. I guess you didn't watch that video. Or know that the blueprints for Obamacare were copied from Romney's healthcare plan used in Massachusetts.
Romney's only saying he's gonna repel Obamacare to get gullible Republicans like yourself to vote for him. He's infamous for being a flip-flopper; he's not actually gonna do it. You can literally go to Youtube right now and see how two-faced he is. It's like when Obama was going to be the peace-time, pro civil liberties candidate, but did the exact opposite when he got into office. Or when Bush promised a non-aggressive foreign policy when he was campaigning. They're just crooked politicians being crooked politicians.
It's basically come down to "Vote Libertarian" or "Betray the Constitution." I have no doubt you'll gleefully choose the latter.
