This is a historic night. I'm proud of President Obama, and I think that much respect is due to President Clinton. He played an important role with a key demographic.
It's also a good night for progressive values and candidates in general though, which says a lot. Marriage Equality passed by popular vote in two states, two new Democratic senators were elected (both progressive and powerful women). One, Elizabeth Warren, accomplished this against a popular incumbent. Last but not least, legalized marijuana passed in CO and WA.
All of this was accomplished amidst obstacles--long lines, new voter id laws, not to mention a hurricane that devastated Democratic strongholds on the east coast. If you lived in a city, especially in a swing state, it was harder to vote this year, harder to register to vote. These are not the accomplishments of a depleted liberal movement or an ineffectual party out of step with the country. Maybe Democrats just need a bit more optimism and conviction.
