Or as Kathleen Parker writes, "When all else is failing, reinvent yourself." Well, maybe that works for some people.

In any case, Jeb Bush does seem to be a nice guy. But his personality is not at issue.

His problem is not just that he's a Bush. His problem is that he seems clueless regarding the purpose of being president of the United States.

My only advice is that he read and think through the Declaration of Independence and U.S. Constitution. If he doesn't understand there's a vision for freedom within the liberating circle of constitutional norms and "enumerated powers," then he really ought to seek a different line of work.

Something among the "really cool things" that he "could do," to borrow his phraseology.

Look: Every job -- from dog-catcher to parent to ice-cream truck driver to governor to actor to pastor to president is about "getting things done," etc., etc.

The real question is: What is it, Mr. Bush, that is specific to the elected office of president of the United States?

There's a very specifiic job description relative to being president. Unfortunately, Jeb and about 200% of the Republican establishment do not appear know what that description is.

Or if they know it, they reject it. Neither option encourages confidence.

If you don't know the job by now, Mr. Bush, why should we hire you?
