So, no, a law can be repealed and rewritten much more easily.
That does not mean the GOP has the gonads to do it. What this essentially did was take the Republican elites off the hot seat so now they can pretend to campaign against Obamacare while supporting it legislatively on the grounds that "it's the law."
Now who is being silly.....I dont see a future congress repealing obamacare....just a bunch of gutless worthless people.
