OBAMA "ON THE VERGE OF BLOWING THE GREATEST GIMME IN THE HISTORY OF AMERICAN POLITICS"

Seems everyone knows it but Obama.

The Democratic presidential candidate's slump in the polls has sparked pointed private criticism that he is squandering a once-in-a-generation chance to win back the White House.

Party elders also believe the Obama camp is in denial about warnings from Democratic pollsters that his true standing is four to six points lower than that in published polls because of hidden racism from voters - something that would put him a long way behind Mr McCain.

The Sunday Telegraph has learned that senators, governors and union leaders who have experience of winning hard-fought races in swing states have been bombarding Obamas campaign headquarters with telephone calls offering advice. But many of those calls have not been returned.

A senior Democratic strategist, who has played a prominent role in two presidential campaigns, told The Sunday Telegraph: "These guys are on the verge of blowing the greatest gimme in the history of American politics. They're the most arrogant bunch Ive ever seen. They won't accept that they are losing and they won't listen."

After leading throughout the year, Mr Obama now trails Mr McCain by two to three points in national polls.
