The unprecedented nastiness of this season’s primary campaign seems noteworthy. Has there ever been a political atmosphere as charged with negativity as this one? Have there ever been so many candidates who’ve had so little to say about what they are actually in favor of? Okay, we did hear some platitudes about “Kansas values.” But mostly we heard negative messages telling us what they were against. They were against President Obama. They were against health care reform. They were against taxation. They were against undocumented immigrants.
