There's hardly any change here in the topline numbers from the R2K poll of Arkansas released last Friday, either in the primary, or especially in the general. (There were also Tom Cox matchups; I'm leaving them out, as he's dropped out.) Undecideds are dropping in the primary, but the real gainer here is "other," probably in the form of previously unknown conservadem D.C. Morrison.
The numbers to note in this poll are the approvals: Blanche Lincoln's problem is that everyone has an opinion of her, and the majority of that is negative: 43/53. Bill Halter, by contrast, is at 47/30. 23% still haven't formed an opinion of him, giving him room to grow. Lincoln, by contrast, has hit her ceiling and is upside down -- not the conditions that get you re-elected.
