“My center is giving way. My right is in retreat. Situation excellent. I attack!”

That’s the message supposedly sent by General Ferdinand Foch of France to his commanding general, Joseph Joffre, during the crucial First Battle of the Marne in September 1914. The French and British counterattacks succeeded. The German Army, after advancing for a month, was forced back.

Here in the U.S., after more than a month of Democratic advances, it’s the Republican center that’s giving way, and some on the political right who are in retreat. The Obama campaign is marching toward the biggest nonincumbent Democratic presidential victory since 1932, and the Democratic Party is fighting its way toward its best overall presidential and Congressional year since 1964.

Situation not-so-excellent. Time for McCain to attack  or, rather, finally to make his case.

The heart of that case has to be this: reminding voters that when they elect a president, they’re not just electing a super-Treasury secretary or a higher-level head of Health and Human Services. They’re electing a commander in chief in time of war.

The McCain campaign intends, I gather, to return to the commander in chief theme with an event in Florida Wednesday showcasing former secretaries of state and retired senior military officers. But why not showcase young Iraq vets instead? These young soldiers and marines can testify eloquently to the success of the surge that John McCain championed, and to the disaster and dishonor that would have followed Barack Obama’s preferred path of withdrawal.
