Well for politicians it's very normal to write a book. It gets your ideas out there for the public record.
I understand that. But now we have a way for politicians who claim they act on principle and principle alone to get their message out in a faster, more effective, 21st century fashion. It's the Blogosphere. That's as much the public record as having a book signing at Borders. The only difference is, there's no payday, just the sharing of ideas and information with much less conflict of interest.
Which is why copyight is eternal.
