(CNN) - John Kitzhaber is bidding for an unprecedented fourth term as Oregon governor.
Kitzhaber made it official on Monday, announcing that he'll run for re-election next year.
The Democratic governor was first elected in 1994 and re-elected four years later. After eight years out of office, Kitzhaber won election in 2010 to an historic third term as Oregon governor.
In announcing his candidacy, Kitzhaber acknowledged that the rocky rollout of Cover Oregon, the state's health care exchange, would be used against him in next year's campaign. But the governor said he's ready to deal with the criticism.
"I'm certainly willing to take a few slings and arrows for the rocky rollout," said Kitzhaber according to local media reports.
Kitzhaber won a narrow victory in 1994, followed by a landslide re-election in 1998. In 2010, he edged out Republican candidate Chris Dudley, a former pro-basketball star, to return to the governor's office.
Two Republicans, state representative Dennis Richardson and rancher Jon Justesen, have announced they'll run for governor next year.
