It appears that the new Republican strategy is, well, the old Republican strategy. We're at war. A little rebranding... a little repositioning. This season, it's not the global war on terror, it's World War III. They're counting on the American people to be unwilling to change leadership in the middle of a war. Republicans, on the other hand, had no trouble running against war leadership during the Korean war or the Vietnam War.

Anybody who wonders how to run against a "War President" can learn from Nixon.
(OK... Nixon wasn't running against the War President (Johnson had dropped out). Nixon ran against the War Vice President, Humphrey, was the candidate. But then again Bush won't be running again either.)
