To see who can get closest to the actual vote count, and to see if there is any collective wisdom in the composite values of multiple predictions, I have put together all the Senate predictions from BMG and RMG.
Here are the straw poll and predictions from RedMassGroup:
So there we have it: BlueMass people overall think it will be a 50-47 Coakley victory and RedMass people average a 50-48 Brown victory, and RedMass predicts a higher turnout (1.2 mil to 1 mil).
The average between the prediction margins, which is a really quick and dirty way to aggregate the percentages, gives an absolutely razor thin 49-48.5 Coakley victory. Apparently, the collective Conventional Wisdom is that this will be an extremely close race.
If you are wondering what that "Model Adjusted" field is, I will post details on that in another post. This is my attempt at creating a prediction model out of this data.
