"Average" is the plain mean of the exchanges that price a party; where only one does, that exchange's price is used. Each party's price comes from its own market, so a race's two sides need not add to exactly 100%, and independents are listed beside the table row rather than on the map. On the House view, a district's two sides are scaled to add to 100% before the seats are added up, a district is a toss-up when neither party is above 60%, and the totals treat districts as independent, so they are a tally of prices and not a forecast of the chamber. Some state markets trade very little, so a price can sit still for hours. Market prices are information, not investment advice. Updated .
