From what I've seen, all the contracts on Tradesports are binary, essentially classical Arrow-Debreu securities. You can make binary spreads, buying BUSH.ELECTORALVOTES and selling BUSH.ELECTORAL+300 to get paid if Bush get between 270 (to win) and 300 electoral votes. In this case the 270 is understood.
