One example.
Romney has promised to repeal Obamacare. Do I believe him? Not really. But if we win the senate and keep the house, it will be the first vote. Because it was ruled a tax, it can be repealed by a majority not 60 votes.
If the congress passes the repeal, what are the chances of a Veto? I would say less than 50/50.
As Don Rumsfeld pointed out: you go to war with the army you have. Mitt’s the General and may lead us to slaughter, but isn’t it better than desertion?
Romney said he is PROUD of Romneycare. He will greatly expand it. By 2016, small businesses as we know it will be on there way to extinction. If you are employed by a small business, start pursuing other options now.
That was just for the purpose of the ruling. Now, no one, even Roberts would dare call it a tax. They will never get 60 votes to repeal.
