For the second time in a month, Barack Obama's campaign has organized a campaign to (a) slime a journalistic critic and (b) try to intimidate Chicago radio station WGN.

David Freddoso attempted to appear on Milt Rosenberg’s WGN radio show last night, and just as when Stanley Kurtz tried to talk on the same show, the Barack Obama campaign organized a disruption of the show.  The campaign sent out an e-mail to supporters in the area sliming Freddoso as an “extreme” hate monger, a “smear merchant”, and attempted to silence him despite Rosenberg having an Obama surrogate on the show:

Chicago radio station WGN-AM is again coming under attack from the presidential campaign of Sen. Barack Obama for offering airtime to a controversial author.

It is the second time in recent weeks the station has been the target of an “Obama Action Wire” alert to supporters of the Illinois Democrat. …

The Tribune-owned station was flooded with calls and e-mails about an hour before an Aug. 27 interview with Stanley Kurtz, a conservative writer who examined Obama’s ties to former 1960s radical William Ayers.

A WGN producer said Monday night’s response was about the same as when Kurtz was on the station.
