Bush's advisers, under pressure from their donors and from falling and stagnant poll numbers, came to the conclusion that a course correction was essential.

Jeb Bush, once a front-runner for the Republican presidential nomination, is slashing pay across the board for his struggling campaign as he attempts to regain traction just 100 days before the party’s first nominating contest.

The campaign is removing some senior staff from the payroll, parting ways with some consultants, and downsizing its Miami headquarters to save more than $1 million per month and cut payroll by 40 percent this week, according to Bush campaign officials who requested anonymity to speak about internal changes. Senior leadership positions remain unchanged.

The campaign is also cutting back 45 percent of its budget, except for dollars earmarked for TV advertising and spending for voter contacts, such as phone calls and mailers. Some senior-level staff and consultants will continue to work with the campaign on a volunteer basis, while other junior-level consultants, primarily in finance but including other areas, will be let go, the officials said. The officials declined to say who would be removed from the payroll or provide an exact dollar figure for the savings.
