“I‘m still for him,” says an adviser to Jeb Bush’s presidential campaign, “but it hasn’t gone very well so far, and we’ve got to face that. It’s going to take some remedying.”

The remedying began Monday with word that Bush has shaken up his campaign before the campaign has even been formally announced. The Bush team sent out word that Danny Diaz, a respected, hard-charging Republican operative, will become the campaign’s manager instead of Bush’s original choice, the highly thought-of Iowa strategist David Kochel, who will move to another senior position in the campaign.
