I think you've misread your own historical example, J.J. Going to Korea was about applying Eisenhower's experience to the mess created by the Democrats. It worked for him because he had credibility on foreign policy while the Democrats had none.
Most people would agree McCain's in the opposite position. He's weak on the economy and is, whether justified or not, closely associated with the incumbent administration who's policies and oversight are being blamed for the current crisis.
A better example might be McGovern's visit to Vietnam after he'd secured the nomination in 1972. An all-but-forgotten event, it did nothing to dispel the impression of McGovern as soft on military issues and foreign policy. It was a publicity stunt that failed badly.
No, this is on a par with Eisenhower, because it goes with two strengths McCain has, bipartisanship and leadership. This isn't really about the economy; it's about leadership. McCain looks like a doer; Obama looks like a talker.
So I assume you are predicting a McCain surge in the tracking polls in the next couple days?
