A far more observant observer than I (I'm damned if I can find where I saw the piece but when I do I'll put up the link. Found it!) has noticed that there is a consistent variation depending on sample size. All the polls in which more than 1,000 likely voters were sampled are strongly in favour of President Romney. With one recent exception, posted since the piece was written, every one of the polls with less than 1,000 likely voters sampled favours Obama.
I haven't yet looked at the internals to see what the Democrat/Republican split is for the smaller polls but I can't help wonder whether those outfits which shill for Obama are too lousy to spend the large amounts of money it takes to phone up 1,000 people to talk to just thirty. Yes, the last figure I saw for poll respondents was just three percent.
My guess is the second biggest loser after Obama on November 6th will be the US media associated public polls.
