I agree with you. I don't think she could win a primary versus Sestak. I was just throwing out other names.
The problem is her base is split. She would win Phill and Montco, but Sestak takes Delco and Chester, and the rest of the state would overwhelming back the Admiral over Schwartz.
On the flip side in the General, Schwartz would ensure almost no risk at all of losing votes out west, in NE or SW PA and even some potential for gain for Toomey (like Erie which likes moderate Republicans and Toomey's bipartisan work could change minds versus 2010). The entire race would come down to Lehigh Valley (where Toomey is based out of it) and Bucks where the GOP has been improving over the last several elections (from matching the state to about four points more Republican than the state).
