Michael Kinsley: Libertarians Rising
To oversimplify: Democrats are for Big Government; Republicans are against it.
To oversimplify somewhat less, Democrats aren't always for Big Government, and Republicans aren't always against it. Democrats treasure civil liberties, whereas Republicans are more tolerant of government censorship to protect children from pornography, or of wiretapping to catch a criminal, or of torture in the war against terrorism. War in general and Iraq in particular--certainly Big Government exercises--are projects Republicans tend to be more enthusiastic about. Likewise the criminal process: Republicans tend to want to make more things illegal and to send more people to jail for longer. Republicans also consider themselves more concerned about the moral tone of the country, and they are more disposed toward using the government in trying to improve it. In particular, Republicans think religion needs more help from society, through the government, while Democrats are touchier about the separation of church and state.
