With the Wisconsin Senate race entering the home stretch, former Sen. Russ Feingold is getting star power from Hollywood, while Sen. Ron Johnson is getting help from Gov. Scott Walker.

The Feingold campaign sent a fundraising email under Silverman’s name, in which she calls the Democrat a “progressive rock star” and “one of the very few totally righteous politicians who has always voted on the right side of history.”

Actor and director Robert Redford made a similar appeal for Feingold in August.

Silverman was a vocal supporter of Sen. Bernie Sanders in the Democratic presidential primaries. She also spoke at the Democratic National Convention in Philadelphia in July with comedian-turned-Sen. Al Franken, where she told  “Bernie-or-bust” holdouts, “You’re being ridiculous.”

Meanwhile, Wisconsin Gov. Scott Walker plans to campaign with Johnson on Sunday in Eau Claire, Green Bay and Waukesha, The Associated Press reported.

The Rothenberg & Gonzales Political Report/Roll Call rates the race as Leans Democratic.
