Sen. Bernie Sanders' campaign is changing who will lead his presidential effort in the crucial primary state of New Hampshire.
The Sanders campaign confirmed Sunday that Joe Caiazzo, the campaign's New Hampshire state director since March, is leaving the position. He will take on the role of Sanders state director in Massachusetts.
Caiazzo is being replaced by Shannon Jackson, a longtime aide to the senator, according to the campaign. Jackson was campaign manager for Sanders 2018 Senate re-election campaign in Vermont.
Sanders has struggled this cycle to maintain the level of support that helped him to a 22-point victory in the 2016 New Hampshire primary. Sanders' campaign manager and some officials endorsing Sanders are hedging expectations about New Hampshire and deny a loss in the state would sink his candidacy.
