I beg to differ. That's just the Santorum spin. Casey has spoken quite a bit about his desire to bring fiscal responsibility to Washington, about the fact that no veteran should have to choose between disability and retirement pay, about investing in early childhood learning to give kids a better start in their education, and about promoting economic growth in PA.
Liberal newspapers even call Casey out, saying he's not campaigning.
He's not issue-oriented? Sure, he'll make a controversial remark here and there but don't say that he doesn't pay attention to issues or that he does nothing.
Do you honestly believe that Casey will have that much of an impact? The Dems will walk all over him. DC won't be like PA - Bobby won't have people adoring him like he does now. They'll show him how things work and he'll get totally used whereas Santorum would continue to lay out how things work in the leadership if re-elected.
