When will these darned Republicans stop their vagina monologue?

Democrats think they have a political winner in the Republicans’ fascination with reproduction at a time when economic production is what voters have in mind. The party is raising money with a petition against the “Republican War on Women,” and 11 Democratic women running for the U.S. Senate are using the occasion to launch a fundraising tour.

They are attempting to tie together everything from last year’s effort to defund Planned Parenthood to the proposed repeal of Obamacare (which expanded coverage of mammography and birth control). And Obama campaign strategists tell me they are confident that the two leading Republican presidential candidates, a Mormon and a devout Catholic, will have difficulty beating the rap that the party is obsessed with reproduction.

Evidence that the Republicans realize they’re in a pickle: Mitt Romney spontaneously flip-flopped on his initial opposition to the Blunt amendment, which would also provide employers with a moral opt-out from other elements of Obamacare. Romney first said that “questions about contraception within a relationship between a man and a woman, husband and wife, I’m not going there.” But he quickly reversed himself in favor of the amendment, aligning himself with Rick Santorum, who has voiced doubts about the constitutional protections for birth control.
