There are several possible unintended consequences if the health-care law is thrown out or neutered. Here are two.
First, into the vacuum created by the overturn roars a single-payer system, abhorred by most of the critics of the current law. Whatever one thinks of President Obama's plan, it leaves the current system of private health insurance intact. If the mandate is illegal, one solution that would solve access, if not cost, would be government health care, without running afoul of the judges.
Another consequence if the Supreme Court throws out the law would be the energization of Democratic activists. They are quiet now, while the right is fired up and ready to go. They will come home if Obamacare is defeated by the same judges that installed George W. in office. For Republicans, file all this under "wishes, careful."
