Judd headlined Saturday's 80th anniversary celebration for Indiana Planned Parenthood, which Judd said was evidence that the organization's efforts on behalf of women were having a positive impact.
"I have said countless times that unless you are delivering a product and service that is really needed and unless you are doing it really well, you don't stick around for 80 years," said Judd.
Judd, who has been mentioned as a possible challenger to Senate Minority Leader Mitch McConnell, R-Ky., urged women in to remain politically active, The Indianapolis Star said Sunday.
"Women must come forward," she said.
Judd hails from neighboring Kentucky but has a unique tie to Indiana. Her husband, Dario Franchitti, is a three-time winner of the Indianapolis 500.
Franchitti didn't attend the event but Judd sent him a long-distance compliment by describing him to the audience of 500 people as "my hot husband."
