Former “Happy Days” cast members will unite for a virtual fundraiser for the Democratic Party of Wisconsin Sunday.

Attendees will include several actors from the Milwaukee-set sitcom, including Henry Winkler, Ron Howard, Don Most, Anson Williams and Marion Ross, as well as Lowell Ganz, who was a writer and supervising producer for the show.

Among the absent cast members is Scott Baio, who is one of President Trump’s most vocal Hollywood backers.

Viewers will be able to join the event with a donation of $1 or more, according to the Milwaukee Journal Sentinel.

Howard tweeted about the event Monday, calling 2020 “the most important election of our lifetimes” and referencing Wisconsin’s status as a battleground state. Winkler also amplified the event on his own Twitter account.

The most important election of our lifetimes is right around the corner and Wisconsin is a must-win swing state. So, I’m thrilled to announce a #HappyDaysReunion to support @WisDems on Oct 25. Chip in any amount to attend – https://t.co/otVhvvojQZ

Numerous TV and movie cast reunions have served as digital fundraisers in recent weeks, including those with cast members of “The Princess Bride,” “Veep” and “Parks and Recreation.”

Several actors from the “Avengers” franchise are set to fundraise for Joe Biden’s campaign with his running mate, Sen. Kamala Harris (D-Calif.), Tuesday afternoon.
