After winning nine states on Super Tuesday, Joe Biden has won landslide victories in three New Jersey Democratic county conventions.
Biden won party votes in Mercer, Burlington and Atlantic.
Party leaders have still not decided whether New Jersey Democrats will have an open presidential primary. U.S. Senator Bob Menendez has proposed a plan to have no organization lines for that race.
The Menendez plan came at a time when some Democrats believed Biden was faltering and Bernie Sanders was surging, and there were still seven Democrats contending for the nomination.
Since Biden’s huge win in South Carolina, the field quickly winnowed to just two, although Tulsi Gabbard technically remains in the race.
In a ranked-choice vote in Mercer on Wednesday, Biden defeated Elizabeth Warren, 946 to 577, with 441 for Sanders.
On Thursday evening, hours after Warren withdrew, Biden defeated Bernie Sanders with 74% of the vote, 98 to 34 in Burlington County. One delegate voted not to endorse anyone.
Biden won 81% in Atlantic County on Sunday. He defeated Sanders by a 205 to 48 vote.
Party by-laws give the three Democratic county chairs — Janice Mironov of Mercer, Joseph Andl of Burlington and Michael Suleiman of Atlantic — the authority to determine which candidate, if any, gets the organization line.
Warren won the first-in-the-state presidential primary in February, taking Hunterdon County on the third ballot by four votes over Michael Bloomberg.
