SOUTH PARK TOWNSHIP, Pa. - Mitt Romney made a last minute plea for votes this morning, urging a crowd at an energy company to head to the polls Tuesday and continue to work on his behalf over the summer.

"And so I come to you the day before a primary, asking for your help," said Romney, speaking at a natural gas and coal energy company. "I need you guys to go out and vote tomorrow."

Pennsylvania, along with Rhode Island, Delaware, New York and Connecticut, will hold its Republican primary on Tuesday.

While Tuesday 's primary became less relevant after former senator Rick Santorum dropped out of the race earlier this month, Pennsylvania is set to be a swing state in the general election this fall.

"I'd like you to go out and vote in your primary and give me your support and show that we're ready and willing to take on President Obama. And then I want you to work over the summer to get your friends to think about voting, convince them that we need to have a president who understands the economy, who knows how to lead because he's actually led before, who will go to work creating good jobs for the American people and will also go to work to make sure that the promise of America is kept," he said.

"I need your help for Nov. 6. So you need to get your friends to vote," said Romney. "You need to pull them out. Convince them to get on our team. Come join us in this effort."
