Conner Eldridge, the Democratic candidate for U.S. Senate against incumbent Republican John Boozman, is proud of some new ads featuring him in his “debate truck” raising questions about Boozman’s unwillingness to debate, his scant record of legislative accomplishment in 14 years and his decidedly low profile. We’d ask Boozman for a response, but he and his staff shun our inquiries, as well as Eldridge’s, as a general rule.
