Can someone explain this whole Kos/Dean story?

[fujiyama]

As far as I know, Kos has been accused of being unethical by someone named Zephyr...because Kos was paid by the Dean campaign. I don't understand how or why this is a problem because Kos always made it clear he supported Dean and apparently there was a disclaimer. How is this wrong? And who is this Zephyr woman? What is her agenda? Is she a dem/repuke? And what is this about a Wall Street Journal article?

Now how does this compare to Armstrong Williams? All I know is that the WH paid Williams to shill for No Child Left Behind.

So can someone explain this? I used to read Kos all the time during the election but I rarely have visited since then.
