California Elections : SMOOTH SAILING

Incumbent Democrat Jesse M. Unruh, who propelled the Assembly speakership into the political big-time in the mid-1960s, has pushed the state treasurer’s post into the financial industry’s spotlight during his three terms. Such is the state of Unruh’s power--and his $1-million-plus bank balance--that the Democrat not only deferred any challenge within his own party but also scared off Republican competitors. His campaign lasted one day: In February he asked voters to return him to office for a fourth term.

Incumbent Atty. Gen. John Van de Kamp, a Democrat, faces Republican opposition--in name only. None of the Republicans--attorneys Lawrence J. Straw Jr., Duncan M. James and Bruce Gleason--has a statewide name or the funds with which to buy one. Van de Kamp, 50, has been most visible in ads opposing the bitterly contested Proposition 51.
