And it's not Brian Nutt.
For the first time in the last decade, Nutt will not be running Corbett's campaign for public office. The job instead will go to Michael Barley, executive director of the Pennsylvania Republican party, who is switching over to manage Corbett's campaign come April 15.
"I'm very excited to have the opportunity to work for him and help him win reelection," Barley, 34, said of Corbett.
Nutt, who ran Corbett's 2010 gubernatorial campaign as well as his prior races for state Attorney General, will still be deeply involved in the governor's reelection effort, Barley said, just not running the campaign's day-to-day operations.
The announcement came on the same day that yet another Democrat formally entered the race to unseat Corbett in 2014. York businessman Tom Wolf, who was also Gov. Rendell's onetime Revenue Secretary, formally announced his candidacy Tuesday, joining what is shaping up to be a crowded Democratic field. John Hanger, Rendell's former Department of Environmental Protection secretary, as well as Max Myers, a businessman and onetime Pentecostal minister, have also declared their candidacies.
U.S. Congresswoman Allyson Schwartz, as well as Pennsylvania Treasurer Rob McCord, both Democrats, have both said they are seriously considering running for the state's top job next year.
And on the Republican side, Montgomery County Commissioner Bruce Castor has said he is contemplating a primary run against Corbett.
The potentially jam-packed field didn't seem to faze Barley.
"I’m looking forward to putting up the governor’s record against any other candidate," said Barley. "I think Gov. Corbett has a great story to tell about his work for Pennsylvania."
