For a beautiful example of how Republicans should be treating the issue -- as one of liberty, not contraception -- check out Senator Brown's op/ed on the regs. Really masterful . . . even to the point of invoking Teddy Kennedy to make his point!
Note also that Brown now leads Warren among independents; they're telling the Suffolk poll that she's "liberal," while he's "fair/fair-minded." There's a lesson in there somewhere for the presidential field -- namely, that a certain degree of temperance just in the way one discusses controversial issues can get you very, very far.
