I'd be interested to know which pollsters are asking respondents:
- if they watched last Thursday's debate
- if they are registered to vote (the last date to register has now passed)
- if undecided, a few more probing questions about style vs substance
Either way, the volatility means that there may only be some polling winners, with some big losers. Will we have a better idea of which companies are the most reliable until after the event?
