Oh really? And what exactly does the early vote in PA say as far as gender and party registration?I would just laugh at him for being stupid. Not only is the ratio wrong, but the trend this year is no different than previous elections.
Silver knows that there are too many unknowns at this stage to make a solid prediction, he is just saying which way it's leaning. That's based mostly on party registration trends, not on early voter demographics.
No one knows how independents are voting, and no one knows what election day turnout is going to look like.
In states like PA, the NPA split is typically 70-30 democrat.
