Charles Krauthammer aims his latest column at the President’s recent remarks about the Supreme Court and its history of deference to the legislative branch.

In his next-day walk back, the president implied that he was merely talking about the normal “restraint and deference” the courts owe the legislative branch. This concern would be touching if it weren’t coming from the leader of a party so deeply devoted to the ultimate judicial usurpation — Roe v. Wade, which struck down the abortion laws of 46 states — that fealty to it is the party’s litmus test for service on the Supreme Court.

With Obamacare remaking one-sixth of the economy, it would be unusual for the Supreme Court to overturn legislation so broad and sweeping. On the other hand, it is far more unusual to pass such a fundamentally transformative law on such a narrow, partisan basis.

Obamacare passed the Congress without a single vote from the opposition party – in contradistinction to Social Security, the Civil Rights Act, the Voting Rights Act, Medicare, and Medicaid, similarly grand legislation, all of which enjoyed substantial bipartisan support. In the Senate, moreover, Obamacare squeaked by through a parliamentary maneuver called reconciliation that was never intended for anything so sweeping. The fundamental deviation from custom and practice is not the legal challenge to Obamacare but the very manner of its enactment.
