While you are considering that, let me try to usher a few objections out of the way:
There are obvious exceptions to my general rule. Democrats favor, at least theoretically, spending less on defense and medicine.
This correlation hasn’t always been true. The British Liberal Party of the later 19th Century, for example, espoused most of the arguments made by American conservatives today for thriftiness, public and private. The equation of liberalism with high prices has simply been a hallmark of our era since roughly the cultural revolution of the 1960s.
I’m not focusing on traditional topics such as taxes and government spending, but instead calling attention to some empirical commonalities, such as that the more liberal a region or institution is, the more expensive it tends to be, and vice-versa. For example, San Francisco, where the average one-bedroom apartment rents for $3,100 per month, voted 84 percent for Obama in 2012.
