The National Republican Senatorial Committee is not officially taking sides in the California Senate primary, but it has formed a joint fundraising committee with Carly Fiorina, former Hewlett-Packard CEO, one of two candidates vying to take on Sen. Barbara Boxer (D).

The NRSC and the Fiorina campaign formed the Fiorina Victory Committee, according to paperwork filed with the Federal Election Commission on Dec. 4. The committee allows the party and Fiorina to split funds raised via joint events or appeals.

The NRSC has not endorsed a candidate in the primary race between Fiorina and conservative state Assemblyman Chuck DeVore, but it has been at odds with the DeVore campaign.

The national party also tapped Fiorina to give the weekly Republican radio address Dec. 5.

The NRSC told Roll Call it is “willing to conduct joint fundraising events with virtually any Republican candidate who asks, provided they have the potential to help the committee raise money in addition to their own campaigns.—

DeVore campaign spokesman Joshua Trevino confirmed that the campaign has not inquired into joint fundraising. “It does not make sense to us to jointly fundraise with an organization that is supporting our opponent,— he said.

The party also has filed the paperwork for a fundraising committee with Kelly Ayotte of New Hampshire and Trey Grayson of Kentucky, both of whom have contested primaries.
