I'm not going to hang my hat on the slim chance of getting this POS bill repealed later. Personally, I'm sick of seeing some Freepers drooling with glee over the passage of this bill, just because they think the Republicans will score some kind of political points in the next election. Screw both of the parties. This is much bigger than parties. The fate of our free society is at stake.
If you think prohibition's unpopularity makes this a mirror comparison, think again. Prohibition = Immensely unpopular. Public Option = Immensely unpopular. Americans have proven that the "gift" of free healthcare is NOT a popular option. It's not the dichotomy of the two examples, but the similarity of public non-support that's important.
As I stated, I'm not saying this would be easy. But you asked for a past instance of repeal. I provided one. And I stand on the comparison.
