I must say that I am not much of a fan of trying to find spurious relationships between long-term economic trends and the political parties who hold office at various times. But I must say I kind of liked this one from Mark Perry:
PS- I was around a dinner table this weekend with a group of Republicans, including some activists. I asked them what exactly they thought Republicans would do next term if they won real gains in Congress. None of them, many hard-core activists, could name anything except divide government and slow the pace of growth. Which I suppose is better than we have now.
