I read several diary entries earlier discussing the "I Switched" Dean ad for WI.
What I didn't see mentioned anywhere is the fact that it will not be the only ad running in WI. It will be part of a set of ads.
From an email from McMahon:
Beginning Tuesday, we're going on the air in Wisconsin with an ad independently created, directed, and produced by grassroots supporters.
The ad will run along with Dean for America ads focusing on Governor Dean's biography and record.
I was one of the folks that weren't overly impressed with this ad, thinking it was the only thing going on the air. But I see some value in a statement from a supporter in addition to biographical and record ads.
