The 2008.PRES.OBAMA Intrade contract now trades at 70.1, whereas the 2008.PRES.McCAIN Intrade contract is currently trading at 29.8 (compared with 69 and 31.4 respectively as reported on yesterday’s update).
The state-by-state contracts continue to imply that Mr. Obama holds a 338-185 “lead” over Mr. McCain (based upon my cutoff price point of 55 for allocating Electoral College votes). Only North Carolina (15 Electoral College votes) qualifies as a swing state according to my criterion on contract pricing and the allocation of Electoral College votes.
FiveThirtyEight.com currently gives Mr. Obama a 345.4 to 192.6 advantage over Mr. McCain.
