Registered lobbying firms in the Golden State brought in $177,359,844 in 2013, according to the latest filings at the Secretary of State's office. That compares with a haul of $172,620,708 the year before.
KP Public Affairs resumed its spot at the top in 2013 after dropping to second-place in 2012. KP's oil industry client -- the Western States Petroleum Association -- spent $4,670,010 on lobbying last year, more than any other interest group registered to lobby California state government. The group worked hard to influence Senate Bill 4 last year, which set new regulations for extracting oil through hydraulic fracturing, known as fracking.
Sacramento lobbying firms also benefited last year from expensive fights over changing workers compensation benefits for professional athletes; a push by the North Fork Rancheria to open a casino in Madera; and a proposal to regulate a new kind of drugs called biosimilars, among other industry turf wars.
