I'm grateful to a reader for restarting the political discussion we had last fall on this blog. I don't know if we can muster again the same passion, but much has happened since--and much has stayed the same. Obama continues to be hugely popular, the GOP continues to be clueless, and Washington proves incredibly difficult to change, no matter which party is given the task. But Obama has been a disappointment for a segment of his liberal base, and a huge disappointment for some. So, there's lots to talk about.
