Alright, so I managed to dig up the raw data by county.[1] I think I crunched the numbers correctly, but I wouldn't bet money on it being 100%. I just took the winning % per county and took a weighted average across the nation. I believe that should give me the desired results. The result set I used was purely presidential votes between only Obama and Romney which gave me some weird stuff like Harris, TX having a majority vote of 49.4% (also the third highest voting county, which hurt the average). Anyway, it was a fun excercise and it appears that pandora is estimated to be 25-30% more accurate than guessing on county/zip alone. I ended up seeing 61.29% as the average "majority" in each county.
