DeSantis replaces campaign manager as he struggles to gain ground against Trump

DeSantis has replaced his campaign manager Generra Peck with his chief of staff James Uthmeier.
The campaign has faced financial troubles, staff cuts, and disappointing poll numbers against Trump.
Peck will stay on as chief strategist, while David Polyansky joins as deputy campaign manager.
The shakeup comes before the first GOP debate and ahead of early voting states like Iowa.
DeSantis hopes the changes will help reset and streamline his campaign to be more competitive.
