The new SurveyUSA poll of the California Senate race gives Republican Carly Fiorina a narrow edge over incumbent Democrat Barbara Boxer.
The numbers: Fiorina 48%, Boxer 46%. The survey of likely voters has a ±4.2% margin of error. In the previous SurveyUSA poll from three weeks ago, Fiorina was actually given a wider lead of 47%-42%.
Other pollsters have generally been kinder to Boxer, showing her with narrow leads. As such, the TPM Poll Average gives Boxer a slight edge of 46.3%-44.4%, though Fiorina is also gaining. In either case, it seems clear that this race will be hotly fought through election day.
