Newt Gingrich continues to be...well, Newt Gingrich.
He seems to think that McCain suspending his campaign (except for the television appearances made by his proxies, the commercials still running in swing states, and the fact that none of his campaign offices stopped what they were doing) ranks right up there with Eisenhower's "I will go to Korea" pledge.
However, as Daniel Larison, writing in The American Conservative (no kidding) notes:
Gingrich likens [McCain's stunt] to Eisenhower’s “I will go to Korea,” but unlike Eisenhower and the Korean war McCain has no credibility concerning the crisis he is supposedly addressing. In the end, knowing when you can contribute something and knowing when to avoid complicating an already difficult situation by intruding on ongoing negotiations is what separates grandstanding from leadership. It is what separates the simple egomaniacs from the ambitious pols who nonetheless have some idea what public service is. McCain’s belief that he is indispensable in a time of crisis is the surest sign that he is unfit for any office in republican government, much less the chief magistracy of the Republic.
