Three-term Democratic Sen. Barbara Boxer is leading Republican challenger Carly Fiorina by 47 percent to 41 percent with 12 percent undecided, according to a Field poll
conducted Sept. 14-21. The margin of error is 4.1 points.
Boxer's margin over Fiorina, former chief executive of Hewlett-Packard, has been creeping up ever so slightly compared to previous Field polls. In March, she led 45 percent to 44 percent; in July, her lead was 47 percent to 44 percent.
In surveys by other pollsters that we have reported, Public Policy Polling
had Boxer ahead by 50 percent to 42 percent in a poll conducted Sept. 14-16; Boxer led 46 percent to 44 percent in a poll conducted Sept. 11 by Fox News/Pulse Opinion Research
; Fiorina led Boxer 48 percent to 47 percent in a Rasmussen Reports poll
conducted Sept. 6; and Boxer ran ahead of Fiorina 48 percent to 44 percent in a CNN/Time/Opinion Research poll
conducted Sept. 2-7.
Boxer and Fiorina supporters are highly committed to their choices with two-thirds of them describing their vote as a preference for their candidate rather than a vote against the opponent.
Boxer is seen unfavorably by 48 percent and favorably by 45 percent, with 7 percent undecided, an improvement over July when she was viewed unfavorably by a 52 percent to 41 percent margin.
Fiorina is still not known enough to 28 percent of voters for them to express an opinion about her. Among those who have one, she is seen unfavorably by 38 percent to 34 percent, which is a turnaround from July, when she was viewed favorably by 34 percent and unfavorably by 29 percent. In July, 37 percent were not able to offer an opinion of her.
