A new USA TODAY/Suffolk University Poll of people who are eligible to vote but probably won't favor Barack Obama's re-election over Mitt Romney by more than a 2-1 margin.

That should be a serious concern for the Obama forces.

An accompanying story written by USA TODAY political reporter Susan Page breaks down the numbers from the poll, which surveyed 800 adults nationwide.

The story/poll confirms the fact that if the Obama forces can successfully register and get their people to the polls in November, they have a good chance of getting the president re-elected. But it won't be easy when the reduction of enthusiasm for Obama is so evident, particularly among some who were so impassioned in their support for him in 2008.
