WASHINGTON — The United States midterm elections have had almost everything, except a vision for governing.

The Republicans ran on hating Obamacare and accusations that President Obama displayed a lack of leadership on the Islamic State’s terrorism and Ebola. Scott Brown, the Republican candidate for Senate in New Hampshire, even tried to blame his opponent, the incumbent Democrat Jeanne Shaheen, for the possibility that terrorists infected with Ebola might come across the Mexican border.

Democrats leveled charges that hard-hearted Republicans would slice Granny’s Social Security and throw her off the Medicare rolls while denying younger women access to contraception. Republican critics refer to Senator Mark Udall, a Colorado Democrat, as Mark “Uterus” for his emphasis on women’s issues.

A national campaign that will cost about $4 billion, thanks to outside money unleashed by a Supreme Court decision, has featured little discussion of issues that the next Congress will face.
