Independent groups have spent more than $20 million on state legislative contests ahead of Tuesday's election.
The heaviest spending has occurred in two Sacramento-area seats so far. Independent expenditure committees reported spending nearly $2.7 million through Oct. 30 on the 5th Senate District battle between Republican Assemblyman Bill Berryhill and Democratic Assemblywoman Cathleen Galgiani. The Stockton-based seat is one of three swing districts that could determine whether Senate Democrats win a two-thirds majority in the upper house.
The 8th Assembly District is home to the second most expensive race, with outside groups dropping more than $2.5 million. Democrat Ken Cooley and Republican Peter Tateishi are fighting for that suburban Sacramento seat.
Spending by independent expenditure committees is certain to increase in the last week of the campaign, as the groups make their final appeals to voters. The committees can raise and spend unlimited amounts on state elections, provided they do not coordinate with candidate campaigns.
