John McCain and the Supreme Court

Erika Holzer sends a link to a compelling WSJ article titled “McCain and the Supreme Court.”
Its key points are:

…the gulf between Democratic and Republican approaches to constitutional law and the role of the federal courts is greater than at any time since the New Deal. With a Democratic Senate, Democratic presidents would be able to confirm adherents of the theory of the “Living Constitution” — in essence empowering judges to update the Constitution to advance their own conception of a better world. This would threaten the jurisprudential gains of the past three decades, and provide new impetus to judicial activism of a kind not seen since the 1960s.

And:

On Jan. 20, 2009, six of the nine Supreme Court justices will be over 70. Most of them could be replaced by the next president, particularly if he or she is re-elected.

And:

By all accounts, Mr. McCain is more electable than Mr. Romney. He runs ahead or even with Hillary Clinton and Barack Obama in the national polls, and actually leads the Democratic candidates in key swing states like Wisconsin. Mr. Romney trails well behind both Democratic candidates by double digits. The fundamental dynamic of this race points in Mr. McCain’s way as well. He appeals to independents, while Mr. Romney’s support is largely confined to Republicans.

The authors conclude that McCain is the only remaining candidate who is both electable and would not choose blatantly liberal Supreme Court justices.
Which is unsettling, to say the least.
