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.
