Gov. Doug Ducey raised more than $2 million more than his Democratic competitors for the 2018 governor’s race. Sen. Steve Farley, a Tucson Democrat who’s challenging Ducey, raised more than his party-mate, David Garcia, a professor. Both Democratic candidates had spent a good chunk of the money they raised so far. Farley collected more than $500,000, mostly from individual donors. Farley has spent more than half of what he raised so far, largely on staffing, and has $232,000 cash on hand.
