PHILADELPHIA (CBS) — The National Constitution Center gave youngsters – below the legal voting age – a chance to register their preferences in Tuesday’s presidential election.

It’s unscientific, but it may be a bellweather of how things could turn in Philadelphia.

Jenna Winterle is in charge of special events for the center. She supervised the “Gumball Vote.”

“Drop a red gumball for Mitt Romney,” Winterle says. “You can drop a blue gumball for Barack Obama.”

Judging by the tubes holding the gumballs, it’s a landslide victory for Obama.

A group of visiting children from Delaware County had plenty to say about their votes.

“Barack Obama. Barack Obama. I know he cares a lot about education.”

(ABRAMS: Who did you vote for?)

“I voted for Barack Obama. I’ve done some research about Mitt Romney and Barack Obama and I thought I agreed with Obama.”

“I voted for Mitt Romney.”

(ABRAMS: Why did you vote for Mitt Romney?)

“Because I think he has good ideas for health care.”
