It costs, on average, $1.1 million to win a seat in the California Senate, according to Maplight.org. As of the reporting period ending in 2017 for the San Gabriel Valley race to replace Sen. Ed Hernandez, Mike Eng has $1.156 million; Susan Rubio $306,000; everyone else either has dropped out (Vicky Martinez) or not reported any contributions (Monica Garcia, Michael Adams, Ruben Sierra). The only other money in the race is in a fund controlled by disgraced Roger Hernandez. I hear he’s chasing the cannabis train, but who knows.
UPDATE: This is cash on hand. The candidates have spent some of the money they have raised.
