The 2008.PRES.OBAMA Intrade contract now trades at 87.2, whereas the 2008.PRES.McCAIN Intrade contract is currently trading at 13.3 (compared with 88 and 12.8 respectively as as reported in my last update on October 26).

The state-by-state contracts now imply that Mr. Obama holds a 364-174 “lead” over Mr. McCain (based upon my cutoff price point of 55 for allocating Electoral College votes), with none of the 50 states or the District of Columbia falling into the “swing” state category.  Since my last update, Indiana (11 Electoral College votes) has moved from Mr. Obama’s column into Mr. McCain’s column.

FiveThirtyEight.com currently gives Mr. Obama a 348.2 to 189.8 advantage over Mr. McCain.
