@Frederick:
Actually.. the ACA was not Obama's invention.. but Hillary's. When Hillary was the first lady under President Bill Clinton, she came up with a socialized healthcare plan, and she was laughed at by both Republicans and Democrats.
Trump is going to have a massive number of new supporters who are currently being forced to purchase healthcare who will no longer be required to buy it.
Hillary's healthcare plan was very different from ObamaCare. ObamaCare is based off a plan from the Conservative Heritage Foundation think tank. The plan was kicked around in Congress by REPUBLICANS for a couple of decades. It was always their plan.
Then Governor Romney faced with huge healthcare costs due to the amount of uncompensated care given to "freeloaders" as he called them took the plan and implemented it in Massachusetts. Before RomneyCare (and later ObamaCare) people could just go to the ER and never pay the bill. Those costs were forced onto taxpayers and people who had insurance. RomneyCare and ObamaCare ensured that everybody paid something even if it was just a fine.
Romney campaigned against his own healthcare plan when he ran for President which was a huge mistake and likely cost him the election. It seemed like such a big deal back then. Now we have a President who is against stuff he was for just five minutes ago.
