It's a good article and definitely supports its claims on social movement to the left. I think this is generally true. More and more people are taking the attitude that people should be allowed to do with themselves what they want. What it doesn't do a good job is movement to the left on financial issues. Equality etc., beyond some reference to socialism. The idea of upward mobility is so strongly ingrained as part of US's dogma, even pushing it a little to the left is always going to be hard.
