What I want is a non-internal poll of this race. The last one we have is from SurveyUSA, which showed Nunn trailing by 6. The internals (on both sides) are showing radically different results from that, and it seems sort of odd that a republican firm would show a bigger Nunn lead than a PPP internal would. Still at Lean R for now. Going to wait for a poll that isn't an internal before totally invalidating SUSA and moving this to Toss-Up.
If the internal is a REPUBLICAN internal, the argument that it's an internal really can't be used to invalidate a DEMOCRAT leading. Internals don't use an inherently worse methodology; they are just inherently biased. Since this poll found the opposite of what you'd expect from a biased internal, the point is moot and lends the poll even more legitimacy.
