The race to unseat U.S. Sen. Cory Gardner continues to expand as Trish Zornio, a Superior resident and scientist, announced Saturday she’ll seek the Democratic Party’s nomination. Zornio, who made her announcement as thousands of women were expected to march in the third annual Womxn’s March on Denver, said it was time for Colorado to elect its first woman senator. “I’m running because we need to think forward and solve the problems of tomorrow, not only the problems of yesterday, the way I have done my entire career,” Zornio said in a release.
