“We were talking to our staff and our field organizers, they’re all 25 or 22 and we were talking to them.  And I said, well, how are things looking?  And they seemed pretty confident,” said Obama.  “And I looked at David Plouffe, some of you know he’s my big campaign pooh-bah, smart guy, but Plouffe and I looked at each other and we said, you know what, we’re no longer relevant now.  We’re props.  Because what’s happened is now the campaign falls on these 25-year-old kids who are out there knocking on doors, and making phone calls.” 

Obama had made a similar remark during the Virginia rally Saturday to play up the importance of his ground-game and having voters turn out on election day.

In New Hampshire, he told voters that the election was “now up to you.”

“That’s how our democracy works, right -- that ultimately, it’s up to you.  You have the power.  You will be shaping the decisions for this country for decades to come right now, in the next two days,” he added.

Both Obama and GOP challenger Mitt Romney barnstormed in key swing-states on Sunday looking to shore up their supporters with two days left until voters head to the polls.

The Obama campaign has touted its ground game efforts, arguing that its large number of campaign offices and infrastructure in key battleground states will give it the edge. 

But the Romney campaign has touted their advantage from outside spending groups which have funded phone banks and direct mail to mobilize voters.
