MORRISON, Colo. - An overflow crowd cheered Mitt Romney and Paul Ryan during their Colorado rally at Red Rocks on Tuesday night.

"Our campaign is about getting the economy going, getting good jobs for the American people," the Republican presidential nominee told the energized crowd. "Leading in the world. Protecting freedom and creating a … prosperous future."

Romney campaign officials told 7NEWS they distributed 25,000 tickets for a venue that seats about 10,000 people.  An additional seating area with television screens was set up for the overflow crowd.

The rally's star power ranged from singer Kid Rock and New Mexico Gov. Susana Martinez.

With early voting underway, the rally was a way to seal the deal in a swing state where the polls are tight and electoral votes are precious.

"We want to bank all those votes so that on election day you go can get people to polls that otherwise wouldn't get there," said Romney, the former governor of Massachusetts.

President Barack Obama will swing through Denver on Wednesday for an afternoon rally in City Park.

Romney hammered away at his campaign themes as he and President Barack Obama race into the final 14-day sprint before Election Day.

In the panoramic Rocky Mountain showcase, Romney drove home the Republican ticket's free-market principals of less government spending, lower taxes and how this would generate new jobs.

"Paul and I can handle two more weeks of attacks, but I don't think America can handle four more years like the last four years," Romney said.

The Obama and Romney campaigns are riveted on locking down support in the nine states whose electoral votes are still considered up for grabs: Colorado, Iowa, Florida, New Hampshire, Nevada, North Carolina, Ohio, Wisconsin and Virginia.
