And would you believe that the Kennebec Journal would run his letter without identifying him as an elected Republican official?
Look, this doesn't even qualify as astroturfing anymore.
It's just Republicans spotting an opportunity--the failure of the Kennebec journal and other papers to exercise anything like control of their letters sections--and taking advantage of it.
At a certain point, the onus shifts to the Allen campaign: Either they need to make an issue of this practice or admit that they're content for Sen. Collins to receive a steady trickle of positive publicity in letters pages across the state.
Or they need to flood the papers with letters in the same way the Collins folks have.
