"We are one week away from changing America."

CNN) -- Sen. Barack Obama told voters on Monday that "we are one week away from changing America."
Delivering what his campaign billed as his "closing argument," Obama told a crowd in Canton, Ohio, that "there's so much at stake" in the week ahead.

"We cannot let up for one day, one minute, or one second in this last week. Not now," he said.

The Democratic candidate, who has a sizeable lead in national polls, warned against acting as if the election is already over.

"Don't think for a minute that power concedes. We have a lot of work to do. We have to work like our future depends on it in this last week, because it does depend on it this week," he said."
