Electing a judge for the Santa Clara County Superior Court is usually more about comfort level than name recognition. To put it bluntly: People prefer female judges. That might be why an unknown attorney named Alex Cerul listed his first name as Alexis on the ballot for the June 5 primary. Cerul, a staff attorney for the county, faces the battle-tested Paul Colin out of the District Attorney’s office. With more than 35 judges endorsing Colin in the race, one would think the deputy DA is a shoo-in to replace the retiring Jerome Brock on the bench (he got Brock’s endorsement). But insiders think Cerul has a shot based on “The Ritchie Effect,” named after the shocking 2008 upset scored by Superior Court judge Diane Ritchie.
