Following the Democratic sweep at the top of Pennsylvania's ballot this past election three prospective candidates are already sending out strong signals of interest in contesting Republican Gov. Tom Corbett's re-election bid two years from now.
 
York businessman Tom Wolf, Philadelphia millionaire Tom Knox and state government veteran John Hanger said in recent telephone interviews they are seriously considering seeking the 2014 Democratic nomination or have already decided to run.
 
Former U.S. Rep. Joe Sestak, a retired Navy vice admiral who narrowly lost his 2010 bid for U.S. Senate has made it known he is "very interested" in returning to public service but won’t discuss his plans for 2014 at this point.
 
Several other Dems have not ruled out campaigns, including Allentown Mayor Ed Pawlowski, state Treasurer Rob McCord and retiring state Auditor General Jack Wagner.
 
The state's best-known Democrats - U.S. Sen. Bob Casey, who was re-elected this month, and former Gov. Ed Rendell have made it known they do not intend to run.
