Blanche Lincoln fares a little better in R2K's first look at the Arkansas Senate race than she did in the recent PPP poll, which had her trailing state Sen. Gilbert Baker by 2 points. Here, she has a 7-point lead on Baker, and also beats her goofier GOP opponents by margins ranging from 8 to 19 (in the case of state Sen. Kim "That Jew" Hendren).
Still, Lincoln shouldn't be resting on her laurels. She's polling well below the 50% mark, and her approvals are a net negative: 43/49 (with only 17% "very favorable"). Her opponents remain largely unknown, with "no opinion" ranging from 73% for Baker and 75% for Curtis "Shots and Visa" Coleman, to 85% for Cox and Hendren. One finding that might give her a little breathing room, though, is that Arkansans support creation of the public option, 55-38 (when the interviewer fully explains it and doesn't just say "public option")... assuming, of course, that she's actually interested in what her constituents think about the matter.
