Katy Perry rocks the vote

Katy Perry stumps for Obama.

The pop singer headlined a Las Vegas, Nevada campaign stop as the U.S. President continued a two-day blitz of swing states.

Perry, performing in a tight dress resembling a voting ballot, encouraged young voters to play their part in the election.

SOUNDBITE: Katy Perry, singer, saying (English):

"How many of you guys are 18 in here? This is your first time, right? Let's do this tomorrow. You know, I got my poll outfit sorted, okay? Because when I go to the polls in California, it's going to be on point. It's going to be red, white, and blue for you now who."

And the President argued his case to be re-elected.

SOUNDBITE: President Barack Obama, saying (English):

"We haven't finished everything we set out to do in 2008, but you know every single day I set foot in that office, I am thinking about you. I am fighting for your families."

Obama is expected to travel to swing states Virginia and Ohio before stopping in Illinois to cast his own ballot.
