MADISON, WI -

Planned Parenthood Advocates of Wisconsin is endorsing Democrat Mary Burke in the governor's race, even as another Democratic candidate considers challenging her.

Planned Parenthood executive director Tanya Atkinson said Wednesday that Burke is the only candidate with a clear path to victory. The other Democrat considering running, state Sen. Kathleen Vinehout, has a checkered history with Planned Parenthood.

Vinehout received the group's endorsement in 2006 when she ran for the Senate. But Planned Parenthood rescinded its backing after Vinehout authored an amendment to allow pharmacists and pharmacies with religious objections to refuse to dispense birth control to women.

“We believe in Mary’s vision for the state and we see a clear path to victory in 2014 with her," said Tanya Atkinson, Executive Director of Planned Parenthood Advocates of Wisconsin. "Wisconsin women and their families are ready for an experienced leader who will respect our freedoms and advocate for policies that benefit the health and economic well-being of women, their families and our community. It is time for us to make history by electing the first woman governor of Wisconsin who will restore equal opportunity for all regardless of gender, income or where we live.”

No other Democrat has announced plans yet to challenge Republican Gov. Scott Walker.

Atkinson says Burke offers a clear contrast to Walker, who cut funding for Planned Parenthood as governor.
