The perfect leftist world

A few weeks ago Bookworm ask her readers to describe what an American theocracy would look like. That got me to thinking. What would an America in which all three branches of government were firmly controlled by the American left look like? Think President Cindy Sheehan, Secretary of Defense Al Franken and Speaker of the House Catharine MacKinnon. It is one thing to be the party out of power, taking pot shots at those who actually have to govern. It is quite another thing to actually govern, especially in post 9/11 America. Anyway, how would a leftist America conduct itself in the world? Indeed, what would these folks do to America itself? And how would the rest of the world react? I look forward to your speculations and ideas.
