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.
A small group of gun control advocates protested outside Mitt Romney's campaign stop in Golden on Thursday.
About a dozen members of Colorado Ceasefire and Mayors Against Illegal Guns demonstrate outside the Jefferson County Fairgrounds in Golden.
Mayors Against Illegal Guns is led by New York City mayor Michael Bloomberg and Boston mayor Thomas Menino. The group is pushing for both Romney and President Barack Obama to come up with a plan to address gun violence.
Colorado Ceasefire is led by Tom Mauser, whose son was killed in the 1999 Columbine shootings.
