Indiana Rep. Mike Pence (R) announced Thursday he's running for governor in 2012.
"I'm in this race," the congressman said in a Web video where he appears with his wife, Karen.
There was speculation earlier this year that Pence would opt to run for president, but he ruled himself out of the field in January.
In his announcement video, Pence praised current Gov. Mitch Daniels (R) for his "capable leadership."
"Indiana has set the pace in fiscal responsibility, job creation and reform," he said. "But our work isn't over. To keep Indiana growing, Hoosiers know, we must have principled leadership at every level to make the right choices."
He added: "Freedom's work is never done."
Indiana Democrats were quick to tar Pence as a Washington insider.
"Congressman Mike Pence loves Washington, so much so that he made his campaign announcement from there instead of heading back to the heartland and standing with the Hoosiers he wants to represent," Dan Parker, the chairman of the state Democratic Party, said in a statement.
"Hoosiers cherish compromise, and we need leadership that can go beyond party lines, work across the aisle to solve our economic challenges and create the jobs we so desperately need in Indiana. No part of that sentence describes Congressman Mike Pence.”
