Richard Moore spent $1.4 million in 2007.

The Democratic gubernatorial candidate's biggest expenses last year were salaries and related payroll expenses for his campaign staff.

(He spent $1.9 million since his re-election as state treasurer in 2005.)

He paid the Benenson Strategy Group $208,442 for research, a firm owned by campaign manager Jay Reiff $138,115 for consulting, DWD Software Development of Raleigh $137,711 for account management and services, and Dixon/Davis Media Group of Washington, D.C., $93,690 to produce TV ads.

In addition, he spent $23,660 on rent for a Raleigh office. 

He also paid a Wendell man $2,547 for janitorial services. 

Richard Moore says his own poll shows a closer race among state workers.

The state treasurer's campaign hired Benenson Strategy Group to survey likely Democratic voters statewide.

They were asked: "If the Democratic primary election for Governor of North Carolina was
held today, and the candidates were Beverly Perdue or Richard Moore
[rotate names] for whom would you vote?"

Campaign manager Jay Reiff said the respondents who said they worked for state government or were state retirees were closely split: 32 percent backed Lt. Gov. Beverly Perdue, while 30 percent supported Moore.

Thirty-eight percent said they did not know.

The margin of error for the entire survey was plus or minus 3.1 percentage points. The Moore campaign did not provide other data from the poll.

Earlier: Perdue leads Moore 47-32, according to a poll of members of the State Employees Association of North Carolina.
