U.S. Senator Bernie Sanders of Vermont is running for re-election as an independent this year. He received enough write-in votes in the Progressive Party to be its nominee, but he turned it down. He also received enough votes in the Democratic primary to be the Democratic nominee, but he turned that down also. See this story.
The Progressive Party had no statewide candidates printed on its primary ballot, but enough write-ins were received for the party to nominate for Lieutenant Governor and Auditor. The write-in winners for those offices did accept the Progressive Party nomination. They are David Zuckerman for Lieutenant Governor and Doug Hoffer for Auditor. Both are incumbents. Zuckerman is a member of the Progressive Party, and Hoffer is a Democrat. Vermont allows fusion, and Zuckerman will be on the November ballot as “Progressive, Democrat” whereas Hoffer will be on as “Democrat, Progressive.”
