CASPER (WNE) — Former Vice President Joe Biden handily won Wyoming’s Democratic caucuses, taking home nearly three-quarters of the total vote and more than two-thirds of its delegates. The caucus was conducted completely by mail-in ballot due to concerns about the COVID-19 outbreak, which caused the party to cancel the in-person portion of its caucus. The state party announced the results on Sunday.

With 72.2 percent of the vote, Biden will now take 10 delegates to the Democratic National Convention. His main challenger, Bernie Sanders, will be bringing four after winning 27.8 percent of the vote. Sanders formally dropped out of the race on April 8 and has endorsed Biden’s candidacy.

Wyoming’s four superdelegates will be automatically pledged to Biden due to party bylaws adopted in 2018.

A total of 15,428 Wyoming Democrats voted in the caucus, including 561 Park County residents. Park County voters broke even more heavily for Biden, with 404 ballots (79.7%) cast for the former VP, 145 (20.3%) for Sanders and 12 for other candidates.

Some 40,400 Democrats were eligible to vote in Wyoming’s caucus, meaning that roughly 38% of them participated. In Park County, about 44% of the 1,288 eligble Democrats voted.

“It’s only April and this has already been a historic year for Wyoming Democrats,” Wyoming Democratic Chair Joe Barbuto said in a statement, offering the party’s congratulations to both Biden and Sanders.

“This record-setting rate of participation speaks to the enthusiasm among Democratic voters about this election and the benefits of ranked choice voting and voting by mail,” Barbuto said. “We look forward to carrying this momentum through to November and electing Democrats up and down the ballot.”
