The weird things is that Atlas loves Mary Landrieu and Mark Pryor but hate Blanche Lincoln when there's no significant difference between the three useless Blue Dogs.
Lincoln was obnoxious with her opposition to HCR. She also stopped supporting EFCA only once it became plausible to pass it. In addition, she had a primary challenge that galvanized the left against her. Not only that, but I doubt her guaranteeing us a seat loss by losing in an enormous landslide bought her any good will. Besides, there's a big difference between hating Blanche Lincoln and supporting John Boozman.
Landrieu and Pryor might oppose Democrats sometimes, but at least they're not saboteurs or liars.
