You can't simply make "tweaks" to the ACA and not create a worse mess. It is far too complicated and nitpicking for that. It needs to be repealed and replaced.

Now, here's a great idea -- why not replace it with the free market. Let people decide for themselves whether they need insurance and negotiate with companies (or doctors) on how much they want to pay?

Oh, right, because then government wouldn't be involved and we all know we the people are smart enough to vote for who will be our master for the next four years, but too stupid to make intensely personal decisions like health care and where we want to spend our money.
