Republican presidential candidate Mitt Romney is giving President Barack Obama's economic policies a failing grade. And he's promising to create 12 million jobs in his first four years in office.

Romney told a Denver-area rally Thursday that his Democratic opponent has disappointed the nation. He shared a report card giving Obama poor marks on job creation, foreclosures and American incomes.

The former Massachusetts governor is also promising to make North America energy independent in eight years.

Romney is campaigning across Colorado on his first day back on the campaign trail after a bumpy overseas trip.

Obama won Colorado four years ago, but polls suggest it will be a tight race this November. The state, like the nation, has an 8.2 percent unemployment rate.
