Of the 20 non-incumbent female candidates the group endorsed during the 2010 midterm elections, 10 were elected to federal office, Mortham said. Success stories include Republican Reps. Sandra "Sandy" Adams of Florida, Nan Hayworth of New York and Kristi Noem of South Dakota.

"It was as grassroots as it gets," Carole Jean Jordan, the group's finance head and a former chairwoman of the Florida Republican Party, said of the PAC's early days.

Since its inception in 2010, the group has ramped up its presence nationwide, with chairs in 26 states to date. On its website, the PAC lists the names of seven Republican members of Congress who support it, including Reps. Lynn Jenkins of Kansas, Cliff Stearns of Florida, and Virginia Foxx of North Carolina.  

The latest set of endorsements from the group was announced last week. Maggie's List trumpeted the candidacies of three New York contenders for Congress. They are incumbents Hayworth and Rep. Ann Marie Buerkle, and Maggie Brooks, a local county executive running in New York's District 25.
