"The days of Harry Truman, FDR, and John Kennedy are long gone."

Well, let's see...

            FDR was a foreign affairs Hawk, a fiscal Liberal and a social Liberal

            Truman was a foreign affairs Hawk, fiscal Moderate and social Moderate

            Kennedy was a foreign affairs Hawk, social Liberal and fiscal Conservative

Yep, Kennedy would not have a chance these days because too many Democrats would call him an extremist.
