DeSantis ditches his campaign manager, but it's a reset that may have come too late

• Ron DeSantis completed his campaign reset by replacing his campaign manager.
• DeSantis elevated, James Uthmeier, who leads his governor's office to right his presidential campaign.
• Uthmeier has no campaign management experience. He is now tasked with engineering a virtually unprecedented comeback.

Florida Gov. Ron DeSantis on Tuesday completed the full-scale reboot of his once-promising presidential campaign, reassigning his campaign manager and elevating a loyal hand from his governor's office.

The news comes just weeks before the GOP field will face off in the first presidential primary debate in Milwaukee, a chance to reverse a summer that has seen DeSantis, Trump's best-positioned challenger, slip dangerously far behind former President Donald Trump in national polling.
