American Presidents are separated into two types: Those that completely change the discourse and those that follow in the paradigm of the last President that created the tone.
The last President that changed the discourse was Reagan: The one before him: FDR.
Now I ask you....when was the last time you heard a debate that centered around whom would create a more progressive tax plan (with less taxes on the Middle class & NOT cutting taxes on the 'job creators'), and whom would create more regulations?
We are on the cusp of a 'discourse change'.
