Despite the persistent gender gap in opinion polls and mounting criticism of their hostility to women’s rights, Republicans are not backing off their assault on women’s equality and well-being. New laws in some states could mean a death sentence for a pregnant woman who suffers a life-threatening condition. But the attack goes well beyond abortion, into birth control, access to health care, equal pay and domestic violence.

Republicans seem immune to criticism. In an angry speech last month, John Boehner, the House speaker, said claims that his party was damaging the welfare of women were “entirely created” by Democrats. Earlier, the Republican National Committee chairman, Reince Priebus, sneered that any suggestion of a G.O.P. “war on women” was as big a fiction as a “war on caterpillars.”

But just last Wednesday, Mr. Boehner refuted his own argument by ramming through the House a bill that seriously weakens the Violence Against Women Act. That followed the Republican push in Virginia and elsewhere to require medically unnecessary and physically invasive sonograms before an abortion, and Senate Republicans’ persistent blocking of a measure to better address the entrenched problem of sex-based wage discrimination.

On Capitol Hill and in state legislatures, Republicans are attacking women’s rights in four broad areas.
