Support for Obamacare is at an all-time low, we don't know how many who signed up will pay (especially when premiums go up in a couple of months), lots of people lost their doctors and their plans and wanted to keep them and are angry, and the law seems to be doing nothing to keep costs down.

Your characterization of the conservative resistance is also typical partisan trash. Most Republicans aren't heartless and evil. The problem is not with the stated goal of Obamacare but with its operation and its structure. All of the attempts to defund and repeal have the stated goal of ensuring that people with preexisting conditions don't suffer from the repeal. It's possible we will get health care reform right after everything else crashes and burns, but Obamacare will go down as a miserable abortion of a law either way. It will either need to be "fixed" (read: overhauled and completely gutted) or replaced.
