Interactive: Many familiar players in East Bay Senate fight

Today’s runoff election between Susan Bonilla and Steve Glazer in the East Bay’s 7th Senate District is the fourth high-dollar race in the region since June 2014. Last year’s ballot included primary and general election fights in the overlapping 16th Assembly District featuring Glazer, Democrat Tim Sbranti and Republican Assemblywoman Catharine Baker.

The elections and offices are different, but the four contests shared many of the same business, labor and wealthy individual donors, campaign companies and outside spending committees, financial disclosure documents show.
