I know we're all in year end mode at the moment. So I wanted to let you know about a discussion we've got going over at the TPMCafe's Coffee House blog. I started the conversation back on the 26th by asking whether there was any single galvanizing event that led to the remarkable turnaround in the president's and the Republican party's fortunes over the last two years. So far we've got answers from Ed Kilgore, E.J. Graff, Mark Schmitt, Jo-Ann Mort, and Todd Gitlin. Join us.
