“DEAN HELLER just took the war against women to the next level,” declared Shelley Berkley on March 1st. Ms Berkley is a Democrat vying to oust Mr Heller, Nevada’s junior senator. Mr Heller had just voted to let employers refuse to pay for contraceptives and other services. Democrats defeated the bill, but the vote had its desired effect. Ms Berkley and other Democrats have a new weapon to fight Republicans. Conservatives can use the vote to bash Democrats with equal gusto.
