A quick summary from Roger Simon:
Both Jeb and Hillary think they want to be president, have had it in their dreams for umpteen years, but now, faced with the reality, they don’t know why they’re doing it. At least they don’t act that way. They are lost people, running not on fumes, but on habit. They’re supposed to run. They were bred to run. But they don’t have a clue where they want to lead the country, not in any passionate sense.
