Barack Obama is likely to pick up 364 Electoral College votes, far surpassing the 270 needed to claim the presidency, by winning battleground states including Virginia, Ohio, Florida, and Colorado, online traders say.

Bettors on the Dublin-based Intrade’s political futures market believe Obama, the Democratic presidential candidate, will prevail in all the states won by party nominee John Kerry in 2004, in addition to picking up other previously Republican strongholds such as Nevada and Missouri. Arizona Senator John McCain, the Republican nominee, would pick up 174 Electoral votes, winning states such as Texas, Indiana and West Virginia.

Obama has opened a 10 percentage-point lead over McCain, 53 percent to 43 percent, among likely voters nationally in a Washington Post-ABC News poll taken Oct. 8-11. That’s up from a 4 point lead in a Post-ABC poll taken at the end of September.
