Spencer On The Attack Again

On the Coeur d’Alene Press Web site, Larry Spencer is continuing his ad attack on incumbent Commissioner Dan Green, with the drop-down ad above. The add includes an implied attack on the Kootenai Environmental Alliance. Spencer was bragging here earlier this week that he has the Press ad space locked up. Where is Spencer getting all his campaign money to run his primary election?

Question: Is Dan Green underestimating Spencer and the possible trap of a closed Republican primary?
