California Sen. Barbara Boxer (D) leads her two potential Republican challengers by double digits, a new Field Poll finds (Sept. 18-Oct. 6, 1005 RV, MoE +/- 3.2%).

In the Republican primary, former HP CEO Carly Fiorina leads Assemblyman Chuck DeVore by just 1 point, with nearly six-in-ten primary voters undecided. Neither is well known around the state, as 72% have no opinion of Fiorina and 82% no opinion of DeVore.
