P.S: Several issues, including my role at Slate, are still to be resolved. But you will always be able to reach this blog at www.kausfiles.com.
Slate editor Jacob Weisberg jokes in the comments: "Nobody else runs for office this year. We have a magazine to put out." As I posted yesterday, Kaus has taken out the papers but hasn't yet returned them.
