New Hampshire Democratic Party Chairman Ray Buckley is expected to announce his bid for chair of the Democratic National Committee Tuesday.
WMUR first reported the news Monday night.
The station obtained an email Buckley sent to state party leaders announcing his plans to pursue the post.
"I hope to bring what all of you have taught me over the years - elections are won in the grassroots - not in D.C., or Concord, for that matter," Buckley wrote. "The DNC from top to bottom needs urgent reform. I hope to bring our New Hampshire common sense to the national party and get us ready for victories in 2018, 2020, and beyond."
Buckley, a five-term state party chair, has said in recent weeks that he's been weighing whether to pursue the chairmanship.
Since 2009, he has served as president of the Association of State Democratic Chairs. He also serves as a vice chair of the Democratic National Committee. He would be the first openly gay chairman of a national party.
Other prominent Democrats have already announced their bids, including U.S. Representative Keith Ellison of Minnesota and former DNC chair Howard Dean of Vermont.
An election is scheduled to take place in Atlanta in February.
