What are the best political magazines in the country?

I prefer ones with a somewhat liberal bent, like The Nation and The Washington Monthly, but I was curious which ones have the best reputation or you've found are the best reads. Not just political, too. I'm thinking magazines like The Atlantic, Harper's, The Economist, Science and News, etc.

If you can also elaborate as to why, that would be cool, too.
