Mitt Romney officially announced he's running for Senate in Utah in a video message Friday.

Key quote: "Utah has a lot to teach the politicians in Washington. Utah has balanced its budgets, Washington is buried in debt. Utah exports more abroad than it imports, Washington has that backwards. Utah welcomes legal immigrants from around the world, Washington sends them a message of exclusion. And on Utah’s Capitol Hill, people treat one another with respect."

The backdrop: Romney's name has been floated for months, and Orrin Hatch announcing his retirement opened the way for him.
