Actor Ron Silver, who won a Tony Award as a take-no-prisoners Hollywood producer in David Mamet’s “Speed-the-Plow” and did a political about-face from loyal Democrat to Republican activist after the Sept. 11 attacks, died Sunday at the age of 62.

“Ron Silver died peacefully in his sleep with his family around him early Sunday morning” in New York City, said Robin Bronk, executive director of the Creative Coalition, which Silver helped found. “He had been fighting esophageal cancer for two years.”

Silver, an Emmy nominee for a recurring role as a slick strategist for liberal President Jed Bartlet on “The West Wing,” had a long history of balancing acting with left-leaning social and political causes.

But after the 2001 terrorist attacks, longtime Democrat Silver turned heads in Hollywood with outspoken support of President George W. Bush over the wars in Iraq and Afghanistan.

Silver spoke at the 2004 Republican National Convention, began referring to himself as a “9/11 Republican” and reregistered as an independent.

In an interview with The Associated Press a month later, Silver said his support for the war on terror was costing him work in liberal-minded Hollywood.

“It’s affected me very badly. I can’t point to a person or a job I’ve lost, but this community is not very pluralistic,” Silver told the AP. “I haven’t worked for 10 months.”

No matter on which end of the political spectrum his activism fell, Silver viewed such involvement as something of a duty for entertainers.

“I think there’s almost an obligation,” Silver said in a 1991 interview with the AP.
