In response to Hansoribrother's comment:
The likelihood of outright appeal is low. Republicans would have to have veto proof majorities in the House and Senate.
There are some good things about Obamacare but they come with a lot of bad things. On top of that is the implementation incompetence and Obama's never-ending abuse of power by issuing edicts. That is only going to make matters worse.
The disaster will continue unimpeded until enough Democrats see their election chances dwindling. In just a short time the generic House poll has shifted dramaitcally to the Republicans. This will force something fix some of the problems and get rid of some parts of the law that are not worth keeping. Call it a rolling repeal and replace.
Another consideration is how many votes are required in the Senate to convict the President on impeachment. If it gets close after the next election and the messes continue, that might force more replacement of the stoopid law that no one read before they voted on it.
You would need to pick up 22 seats in the Senate to remove Obama. It's a fantasy. And even then it leaves Biden in the WH to veto any attempts of repeal.
There's no chance of repeal until 2016, and it won't happen then because the turnout to elect the first woman president will be just as big as the turnout to elect the first black president, and because the GOP does not now, nor has ever had, a viable alternative.
If Obamacare is unpopular leading up to the 2014 mid-terms, a smart Dem can use that to his/her advantage. You can vote for a Dem or Independent who will work to improve the law, or you can vote for a Republican who will continue the futile attempts to repeal it.
