Full Disclosure ...
Only after November's election returns were in did we learn that John Thune's senatorial campaign subsidized Lauck's Daschle v Thune with $27,000 and Van Beek's South Dakota Politics with another $8,000. As Glenn Reynolds and Amy Sullivan have pointed out, there's nothing illegal in that, but it is dubious. Other bloggers who are subsidized are welcome on our blogrolls, but they make no secret of the subsidy. Professor Lauck's chairman or dean may wish to discuss with him professional conflicts of interest in the sources of his income. This one ranks with expert testimony in legal cases as ethical swampland for historians.
Update: At Informed Comment, Juan Cole has some related thoughts about blog trolling and subsidized blogging.
