First, I'm just going to quote Amanda Marcotte, because she put it too well:
If you think you can just repeal half the population’s right to vote because you don’t like the outcome, then why even bother with democracy in the first place?Second, it's a tactical mistake. Generally, politicians don't get elected on the basis of denying rights to the people who are voting for them. Given that women vote at a higher rate than men, any politician associating with Derbyshire or NRO should be toast after this.
Really, this should serve as a meditation on the fact that conservatism in this country isn't about returning to the mom and apple pie 1950s of legend, it's about returning us to the Gilded Age of horror stories.
