Apparently Under the Dome readers are complaining that the Crone-Sinclair poll might be biased, because Brad Crone is negotiating with Beverly Perdue's campaign. For what it's worth, their poll numbers are pretty similar to our latest poll on the race. In fact, their numbers are better for Richard Moore than ours.
Of course, if Crone does end up working for Perdue he should disclose that on any polling that may have an impact on the race. Then it's up to everyone else to judge whether it may be biased or not.
