It's not often that campaigns point to internal polls showing them losing as evidence that they're doing well, but that's exactly what Vern Buchanan, the GOP candidate for Katherine Harris' seat, has just done. A few days ago Dem candidate Christine Jennings released her own internal numbers showing her her up 52-41, and Buchanan responded by disputing those numbers in an interview with the Bradenton Herald. To prove he was doing well, he told the paper that his own internals have him behind, but only "within the margin of error" — and declined to elaborate further. The admission by Buchanan that his own internals have him down suggests that the Harris seat is increasingly likely to go Democratic.
