As Joy Silver prepares to go head-to-head with Jeff Stone in November, she has the powerful endorsement of Moveon.org, a nationwide Democratic political activist group that was born in the late 1990s.

Silver, a Democrat, is challenging Republican incumbent Stone to represent California’s 28th Senate  District.

Over the years, Moveon.org has had a significant impact in supporting Democrats across the country. MoveOn.org was formed in 1998 in response to the impeachment of President Bill Clinton by the U.S. House of Representatives. It is an American progressive public policy advocacy group and political action committee. It has raised millions of dollars for progressive candidates in the United States.

There are more than 11,000 MoveOn members in Senate District 28. They voted overwhelmingly to endorse Silver.

California MoveOn members have been campaigning hard for progressive candidates up and down the ballot, because it believes these candidates will fight to expand health care, implement commonsense gun safety reform, and work for racial and economic justice.

In making the endorsement, MoveOn leaders said, “Silver is an activist and advocate fighting for everyone in California’s communities. She is a small-business owner, affordable housing consultant, and health clinic executive who has been engaged in her community for decades. She was the chief strategy officer for Choices Women’s Medical Centers in New York and served on the board of the American Society on Aging, L-Fund of Palm Springs, and is on the PALS Palm Springs steering committee. In addition to all that, she most recently served as the lead coordinator for Courageous Resistance, part of the Courage Campaign, which is fighting for a more progressive California and the country.”

Stone was elected to represent the 28th State Senate District in 2014.

The district, which is entirely in Riverside County, stretches from the vineyards of the Temecula Valley to the Colorado River and includes the cities of Blythe, Canyon Lake, Cathedral City, Coachella, Desert Hot Springs, Indian Wells, Indio, Lake Elsinore, La Quinta, Murrieta, Temecula, Palm Springs, Rancho Mirage, and Wildomar.
