Although it's an "outlier" in statistical terms, as Nate Silver points out, the latest Gallup poll can't be dismissed.
The poll stealing the headlines this morning is from Gallup, and for good reason: it gives the Republicans a whopping 10-point lead on the generic ballot. This is, in fact, an all-time record for the Republicans: Gallup has been conducting this survey for almost 70 years, and Republicans have never managed to have quite that large of an edge before.
If you're a Dem, or (better yet) a Progressive, one of our best may well lose his Senate seat. Russ Feingold is dead even now with his Republican opponent but... BUT ... his opponent has three times the war chest invested in TV ads. Please, please help Russ.
