The billionaire businessman,who is skipping the first four state nominating contests as part of a long-game strategy to win the party's nomination to face Republican President Donald Trump in the November 3 election,received three of the five votes cast after the stroke of midnight by Dixville Notch residents.
Bloomberg,the 77-year-old founder of the news company that bears his name,was not on the ballot in New Hampshire,where voters are faced with a list of 33 names - including top-tier candidates,former hopefuls who dropped out of the race and also-ran competitors lacking a national profile.
The ritual in Dixville Notch,dating back six decades,gives a candidate brief bragging rights,as state law does not require polls to even open until 11am.
Bloomberg's campaign was quick to seize the moment.
"We're not competing in NH,but Mike still wins Dixville Notch,"his campaign said in an email with a link to a media story about the results from the town in the northern White Mountains near the Canadian border.

While the number of ballots cast there is tiny in the context of the full-state Democratic primary,which drew almost 250,000 voters in 2016,the victor in Dixville Notch has gone on to win two-thirds of the contested major party primaries in the state.
