all the numbers they use are off-the-wall wrong.
The difference between Democrat and Republican is seldom more than 4 points during the Presidential election.
The number of undecideds at this point is closer to 10% than 30% (which is still high for this late in the game)
I will agree that pollsters are probably trying to factor in all of the new registrations, but as word gets out that more and more of those new registrations are bogus, they should adjust their methodology accordingly. Not doing so at the best suggests intellectual laziness, at the worst voter suppression through disillusionment.
first time voters are part of the problem, but don't really get to the heart of their dilemma (and they really do have one). they are trying to anticipate a tsunami of african american voters, even though african american turnout is already sky high in the general. but then factor in the notoriously unreliable "youth vote", which has yet to show up in a single election, but is always going to flood the polls in the
next one, and then try to account for the fact that first time voters typically turn out at about a 25% rate. oh, and we have a woman on the ticket, which could spin things yet again.
the problem is that the accuracy of any mathematical model is usually based on data gathered in the past, and what is about to happen on november 4th is a first-time-ever sort of event.
