Others have suggested it but now it's official: Joe Hoeffel is thinking of running for lt. gov. In today's Inky:
"I am considering it," said Hoeffel, a lawyer in Philadelphia. The governor needs the best possible governing team for his second term."
Hoeffel formerly represented the 13th district (parts of Montgomery County and Philly) in Congress, and held office as a Montco County Commissioner, and state representative for the 153rd district (now held by Josh Shapiro).
Currently the governor and lt. governor run separately but a bill in the state legislator would allow the gubernatorial candidate to select a running mate. If passed it could affect the 2006 election.
