California Senate candidate Carly Fiorina (R) won the backing of the Susan B. Anthony List Candidate Fund.

The endorsement of Fiorina by the conservative anti-abortion group is a blow to state Assemblyman Chuck DeVore (R) who has tried to portray himself as the most conservative candidate in the GOP Senate primary.

"From a pro-woman, pro-life perspective, there could be no greater contrast," Marjorie Dannenfelser, the group’s president, said in a statement Tuesday. "She embraces and advances the rights of women and unborn children, following in the footsteps of the earliest women in politics. Susan B. Anthony and the early feminists understood, as Carly Fiorina does, that undermining the rights of one never advances the rights of another."

Fiorina has staked out a firm anti-abortion position during the Senate primary campaign. In an interview earlier this month, she said her views on the issue came from "experiences."

"My husband's mother was told to abort him," Fiorina told the San Francisco Chronicle. "She spent a year in the hospital after his birth. My husband is the joy of her life, and he is the rock of my life. So those experiences have shaped my view."
