Even if Romney is voted in the odds of the law being repealed are slim.
The House has already drafted a repeal. We need 51 Senators to pass a reconciliation bill that rescinds the tax. The odds are not that bad.
If that fails, the States have options that the GOP Governors have decided to use, if they need to, after the election.
After implementation, there will be ample opportunity to sue under a variety of issues from violation of the Equal Protection Clause to grave harm resulting from the law.
Vote. If you live where fraud is rampant, get certified as an election judge. Refuse to pay the tax under civil disobedience and put your ass on the line.
Or moan and groan and wring your hands and predict ultimate inevitable defeat because Daddy didn’t punch out the bully’s Daddy. That will certainly accomplish a great deal.
