The Susan G. Komen for the Cure Foundation announced plans yesterday to discontinue funding of Planned Parenthood after a seven-year partnership. Planned Parenthood claims that the Susan G. Komen Foundation, “has been pressured by right-wing groups to stop supporting breast cancer screenings for poor women at Planned Parenthood health centers.”

But how much is pressure, and how much is it Komen seizing an opportunity to disconnect themselves from a group whose large taxpayer subsidies have suddenly become a hot-button issue?
