Jonathan Bernstein at WaPo’s The Plum Line:

What happens at the Supreme Court tomorrow is not being overhyped: it really is that important.

[snip]

The Court’s decision will matter, substantively, in two ways. First, depending on what the Court says, either millions of people will soon be able to get health insurance, or they won’t. Either insurance companies will essentially be transformed into regulated utilities — no lifetime limits, no recissions, a tough standard for the percentage of premiums that go to benefits — or they won’t. Either the new efforts to limit the costs of Medicare will continue to be implemented, or they won’t.

The second way this will matter substantively is about the Constitution. The Court may take a major step towards implementing an agenda of returning the Constitution — and the government in general — to how it was before the New Deal. Or it may re-affirm current Constitutional precedents.

Sounds about right. And I’m afraid it’s going to do the former, which will instantly give all the right wing’s pet anti-government causes new leases on life. You thought there weren’t enough judges now? Wait till all the lawsuits are filed against Social Security, Medicare and Medicaid, the EPA, and anything that else that the Commerce Clause has made legal over the past 70 years.
