The 2008.PRES.OBAMA Intrade contract now trades at 77.5, whereas the 2008.PRES.McCAIN Intrade contract is currently trading at 23.0 (compared with 77.2 and 23.9 respectively as reported on yesterday’s update).

The state-by-state contracts continue to imply that Mr. Obama holds a 353-174 “lead” over Mr. McCain (based upon my cutoff price point of 55 for allocating Electoral College votes). At this point in time, Missouri (11 Electoral College votes) is the only “swing” state.

FiveThirtyEight.com currently gives Mr. Obama a 349.4 to 188.6 advantage over Mr. McCain.
