The History News Network recently conducted a non-scientific poll of 109 professional historians and found that 61 percent rate Bush presidency as the worst yet. Thirty-five percent of those surveyed rated him in the bottom ten, and only four respondents put him in the top two-thirds. A whopping 98.2 percent assessed his presidency as a "failure." And that's with 9 months still to go.

For a campaign that sends out so many long emails (and so many emails, period), the announcement from Clinton campaign manager Maggie Williams that Mark Penn is departing from his role as top strategist was notably brief:

After the events of the last few days, Mark Penn has asked to give up his role as Chief Strategist of the Clinton Campaign; Mark, and Penn, Schoen and Berland Associates, Inc. will continue to provide polling and advice to the campaign. Geoff Garin and Howard Wolfson will coordinate the campaign's strategic message team going forward.
