PHILADELPHIA (CBS) – In a big buying weekend, some potential political candidates are shopping around for higher office.

In two weeks, the Pennsylvania Society holds its annual dinner in New York. It’s an event where potential candidates show up; entertain and strut their stuff.

This year, all eyes will be on the Democrats since Republican Governor Tom Corbett is a sure bet to see re-election. Already, the focus is on three people – Montgomery County Commission Chair Josh Shapiro, former Congressman Joe Sestak of Delaware County and Pennsylvania State Treasurer Rob McCord.

Senator Bob Casey’s name is also in the mix, but after just winning re-election, he is as the football teams would say…doubtful as a challenger to Corbett.

The polls say Corbett is vulnerable but since the two term limit started in Pennsylvania no incumbent Governor has been thrown out of office.

The buzz starts early for 2014 because it will take at least nine months to mount a race.
