PHILADELPHIA (CBS) – The Pennsylvania Society Dinner, a collection of all people political, has ended in New York. It’s a weekend of parties and politics — and this year, some news.

The most intriguing story: Pa. Senator Bob Casey has refused to rule out a run for Governor in 2014. Sources close to the Casey campaign say he just refuses to say ‘no’ at such an early date.

If Casey keeps his name out there, that poses problems to the people who say they want to run against Republican Governor Tom Corbett.

They were also at the big social gathering, spreading their interest. They include Congresswoman Allyson Schwartz, who has hired the financial wizard who ran the finances of the Democratic Committee; Pennsylvania Treasurer Rob McCord; and a newcomer, Philadelphia State Senator Mike Stack, who says he’s interested.

Meantime, Montgomery County Commission Chair Josh Shapiro was present, but making no commitments. His fellow commission member Bruce Castor made it very clear to Republican fund raisers that he’s interested in running against Governor Corbett in a primary.

But Casey’s not ruling out a run was the overriding story to come out of the New York gala.
