Former Assembly GOP Leader Bob Naylor of Menlo Park, who once headed the state GOP, left the Capitol years ago to hook up with the Nielsen-Merksamer law firm and become a partner. Hard to imagine a better gig than that, but apparently there is: his own lobbying operation. Naylor, a Yale Law School product, will leave the law firm by the end of the year to start up his own company. He’ll be one of a legion of former lawmakers who become lobbyists and strategists targeting their erstwhile colleagues. Naylor was in the Legislature for eight years, including three as Republican leader, and served when Jerry Brown was governor, so he may wind up renewing old acquaintances. As for the law firm, its name will change to Nielsen, Merksamer, Parrinello, Gross and Leoni. The new lineup, which adds the names of James Gross and Marguerite Leoni, reflects Naylor’s departure and the retirement of John Mueller.
