She's for Lt. Gov. Mandela Barnes.
It's a key pickup as Barnes seeks to stake a claim in his home city of Milwaukee, which looms as a political battleground in a crowded primary field.
Other contenders from Milwaukee include Alex Lasry, on leave from his executive job with the Milwaukee Bucks, state Sen. Chris Larson and Milwaukee Ald. Chantia Lewis.
State Treasurer Sarah Godlewski, who lives in Madison, and Outagamie County Executive Tom Nelson will also try to make inroads in Milwaukee.
Moore was ebullient in her praise for Barnes. They have known one another for years and Moore remarked in the video, "like my mother, his mother was a public school teacher, so you know he has good roots."
