At the moment there are 10 toss up states, 8 of which both candidates are within 3% of eachoter, and 5 of which the candidates are within 2% of eachother. Basically, if party turnout matched 2008 it is likely that Obama will win, if it is closer to 2004 it is likely that Obama will lose ... |
If you have a series of polls, over several weeks, from various polling organisations, including through the debates, and they all fall for the same candidate and it averages out to 4-5% then the state is probably not really a toss up and the 4-5% is likely to be a true difference. Most polls have a 3% MoE, so an individual poll with a 5% margin is a toss up result. But if you get an ongoing trend of ~5% for the same candidate then the meta-MoE across all the polls drops away and moves closer to <1%. A poll of polls that gives a 3-5% lead to one candidate is outside the toss-up zone, but it's not yet in the locked-in zone. Huffington Post calls it leaning, and it also gives a confidence in the lead of the candidate. So a 3% leaning state with a 75% confidence in the lead is still a pretty fragile state, but a betting man would put money on the currently leading candidate. A true toss-up state, within 3%, with a 60% confidence in the lead would not be a good bet for the leading candidate, and it would be a pretty poor bet for the trailing candidate.
It does tend to be the case that low turn out elections favour the right / conservatives. Heck, wet weather favours the conservatives (because it lowers turn out). But because of the ECV it's not actually national turn out that would indicate the likely winner but swing state turn out. So those fragile 7-8 states are the ones to watch in terms of turn out.
