If They Jam It Through - Can It Be Repealed?

If Congress does jam this health care takeover through, the question will be - can it be repealed?
The outlook does not look good but it would be possible with a presidential change in 2012. There are options in 2011 to limit or cut off funding for the takeover.
The main problem that I see - from history - we have seen once Congress gets power over something (Republicans or Liberals) they don't like to give it up. We would really need to have the most ethical Congress in history to get it done.
Don't hold your breath.
