MEGAN MCARDLE ON NORTH AND SOUTH IN THE REPUBLICAN PARTY: “As long as social issues dominate the Republican Party, they will continue losing their north–I had a lot of relatives who at least considered voting for Obama. Ironically, I wonder if the tea parties won’t help bring the two wings of the Republican party together: guns and lower government spending are the two things all members can agree on.” Sounds almost . . . libertarian!
