Wolf, who was revenue secretary under Gov. Ed Rendell, ran briefly for governor in 2010 but dropped out before the primary to turn his attention to saving his family's struggling business. He said the company turned around more quickly than he expected.
He said his business experience - the Wolf Organization employs about 235 people and bills itself as the nation's largest distributor of kitchen and bath cabinetry - combined with a stint in the public sector makes him a strong candidate.
Wolf says he will ante up $10 million of his own and raise an additional $5 million.
Meanwhile, Corbett's reelection effort shifted into gear Tuesday with the announcement that Michael Barley, executive director of the state Republican Party, will serve as campaign manager.
"I'm very excited to have the opportunity to work for him and help him win reelection," Barley, 34, said of Corbett.
Other Democrats weighing a possible run include U.S. Rep. Allyson Y. Schwartz, state Treasurer Rob McCord, former Environmental Secretary Kathleen McGinty, and former U.S. Rep. Joe Sestak. Former environmental secretary John Hanger and minister-businessman Max Myers are also declared candidates.
G. Terry Madonna, a political scientist at Franklin & Marshall College, said such a large field jockeying to take on an incumbent governor is unprecedented in recent state history and suggests the extent to which Democrats see an opportunity. "Most of the primaries have not been about the party trying to wean people off the ticket - it was trying to find a candidate," said Madonna.
Neither the level of Democratic interest nor the governor's weak approval ratings in polls phased Corbett's new campaign chief.
"I'm looking forward to putting up the governor's record against any other candidate," Barley said Tuesday. "I think Gov. Corbett has a great story to tell about his work for Pennsylvania."
