So, given that there is no time for the pollsters to change their methods by then, it might be wise to add nine points to Hillary Clinton's opinion poll numbers, and deduct two from Obama's.
Two different methods producing two different answers would enable the pollsters to treat their results like Groucho Marx's principles, and say "if you don't like my results, I have others".
The current methods used by pollsters to adjust the voter samples are also not considered by the report's authors to be a good predictor of how people feel about the EU.
