Women have watched a chilling cascade of efforts in Congress and a succession of states to turn women into chattel, to shame them about sex and curb their reproductive rights. They’ve seen the craven response of G.O.P. candidates after Limbaugh branded a law student wanting insurance coverage for birth control pills, commonplace for almost five decades, as a “prostitute” and “slut.”

American women have suddenly realized that their emancipation in the 21st century is not as secure as they had assumed. On “Meet the Press” on Sunday, Gov. Bob McDonnell of Virginia, a Republican, had the gall to say this, justifying his support for a bill designed to humiliate women getting abortions by penetrating them with a wand to take a picture: “Every invasive procedure has an informed consent requirement.” What he really meant is that when abortion is an option, informed consent should require an invasive procedure. Along with Rick Santorum’s Taliban views, Mitt Romney suggested in an interview on Tuesday with a St. Louis TV station that to help balance the federal budget he would eliminate Planned Parenthood funding: “We’re going to get rid of that.”

Women who assumed that electing Obama would lift all minority boats are beginning to think: Maybe he’s not enough. If the desire of these conservative male leaders to yoke women is this close to the surface, if they are perversely driven to debase women even though it could lead to their own political demise, then women may require more than Obama.
