I checked out the "late expenditures affecting a candidate" filings affecting Claudia Alvarez's Assembly campaign.
Labor has spent nearly $100,000 in IEs for Jose Solorio this month, but business interests haven't been sitting on the sidelines, either.
JOBS-PAC "A Bi-Partisan Coaliton of California Employers" spent a little more than $85,000 on Alvarez's behalf since May 15 -- basically mailers and polling.
A group called Californians United also made a $30,000 IE for broadcast ads for Alvarez on May 11 (this IE consisted of $24,000 from McLarand, Vasquez, Emsiek & Partners, Inc. of Irvine and $5,000 from O'Brien Mechanical II, Inc. of San Franisco). The same group m ade another $10,000 IE for broadcast ads on May 15 -- and this is where a reader better versed in campaign finance arcana could be of assistance. The IE states it was a $10,000 expenditure, although the filing reports more than $100,000 in contributions from various business interests. Perhaps that means Californians United still has $90,000 left to spend in that IE -- I don't know.
All in all, about $125,000 in business interest spending to elect Alvarez. Solorio and Alvarez may zig-zagging around the political map, but labor and business interests seem pretty clear on where the two candidates are coming from.
