I still think that on most counts, Kos is on higher moral ground than either Armstrong William or Jon Lauck and Jason Van Beek. But Zephyr Teachout's latest post is a serious, serious problem for Kos.
If what Zephyr is saying is true, Kos wasn't on the take for opinions he actually believed in--instead, he went on the take and then changed his public advocation. In Armstrong terms, he wasn't doing it because it's something he believes in.
The problem with payola is that it makes it difficult to tell whether someone is telling you something because they believe it, or because they're being paid. I believe Armstrong when he says he supported Bush's education policy before he went on the payroll.
That doesn't mitigate Armstrong's sins, but it does make Kos's much, much worse: His payola wasn't just icing on the cake. The Dean campaign literally bought his opinion, and stole him away from the Clark campaign. I don't know how anyone could read his site for anything other than entertainment value now.
