The Marstellar Campaign Press Release announcing his run for assembly contained is support for legalization of cannabis and it would be a priority for his campaign. In part, the release stated:

“We have an incredible opportunity under these new fair legislative maps, signed by Governor Evers, to elect people who want to bridge the divide and make real progress on issues that the majority of people in Wisconsin care about – such as expanding BadgerCare, improving affordable housing, legalizing marijuana, and effectively dealing with crime and reckless driving. That is why I’m running.
