It’s been noticed more than a few times that there aren’t many substantive differences between the Republicans and Democrats.
While this is true in many ways for the parties themselves, the Left and Right certainly differ on a range of issues from welfare to abortion to gay rights.
What they have in common — at least the mainstream varieties — is a desire to use the state to shape society in whatever way they see fit. As Andrew Napolitano put it, “We have migrated from a two-party system into a one-party system, the big-government party. There’s a democratic wing that likes taxes and wealth transfers and assaults on commercial liberties and there’s a republican wing that likes war and deficits and assaults uncivil liberties.” And both parties love prohibition, just of different things.
