Bronson Holding Off Challenge From Bell

Pima County Supervisor Sharon Bronson is holding off a challenge from Republican Tanner Bell in early voting.

Bronson has captured 55 percent of the vote, compared to Bell's 45 percent.

Pima County Democratic Party Chairman Jeff Rogers said that "dirty, dark money wasn't enough" to knock out Bronson, referring to the high-dollar campaign waged by Arizonans for a Brighter Future.
