Former Vice President Joe Biden easily won the Kansas Democratic primary on Saturday, which was conducted totally through mail because of the coronavirus pandemic.

Biden had been expected to prevail in Saturday's vote and capture a majority of the state’s delegates to the Democrats’ national nominating commission. Biden took 77 percent of the vote.

While Vermont Sen. Bernie Sanders was still in the race when the Kansas party began mailing ballots at the end of March, he has since suspended his campaign and endorsed Biden’s White House bid.


Biden won 29 delegates while Sanders got 10, inching Biden closer to the number of delegates he needs to clinch the Democratic nomination. He has a total of 1,435 delegates and needs 1,991 to win the nomination on the first ballot at the party’s national convention this summer, a threshold Biden is likely to reach in June after many states postponed their primaries. Sanders has 984 delegates, according to the count by the Associated Press released Sunday.

Sanders easily won Kansas’ caucuses in 2016 over former U.S. Secretary of State Hillary Clinton, riding a surge of enthusiasm among liberal voters and first-time caucus-goers. But the state party mailed ballots this year to more than 400,000 registered Democrats to get a far larger turnout than the 39,000 who voted four years ago.

The primary determined how 39 of the state’s 45 national convention delegates would be allocated. The remaining six are party leaders, including Gov. Laura Kelly and U.S. Rep. Sharice Davids.


Besides Biden and Sanders, Massachusetts Sen. Elizabeth Warren and Hawaii Rep. Tulsi Gabbard also were on the Kansas ballot. Voters also could choose to be uncommitted.

The contest featured ranked-choice voting, allowing voters to pick more than one candidate and rank them. A candidate who failed to get 15 percent in the first round of voting had his or her votes reallocated to voters’ second choices, and the process continued until the only remaining candidates all had at least 15 percent.

Democratic leaders originally had planned to set up polling places across the state in addition to allowing mail balloting. But they scrapped plans for in-person voting at the end of March after Kelly issued a statewide stay-at-home order.

Many Democrats hoped a smooth primary would encourage greater reliance on mail balloting in Kansas’ regular primary in August and its November general election.
