(CNN) - The last uncommitted Republican member of New Hampshire's congressional delegation announced Sunday he will not endorse a candidate ahead of the state's first-in-the-nation primary.
Rep. Frank Guinta said in a statement that he's decided not to endorse anyone but instead work to promote the primary itself, which attracts national media attention and brings millions of dollars into the Granite State. The voting takes place Tuesday.

“Every political official chooses his or her level of involvement and participation in the primary process," Guinta said. "Rather than work on behalf of one candidate or campaign, I have chosen to be an ambassador on behalf of the New Hampshire primary tradition itself."
Guinta said he had personally spoken with each of the Republican hopefuls.
"Starting a year ago, I was actively involved in helping maintain (New Hampshire's) first in the nation status, and have urged all candidates to spend as much time as possible getting to know Granite State voters."
Guinta said he would support whoever emerged as the Republican nominee in the this year's general election against President Barack Obama.
In November, New Hampshire's other congressman - Rep. Charlie Bass, also a Republican - backed Mitt Romney. Sen. Kelly Ayotte also came out in support of the former Massachusetts governor that month.
New Hampshire's other senator, Jeanne Shaheen, is a Democrat, as is the state's governor John Lynch.
