Only a fool (or an ignoramous) would support the federal government being involved in the regulation of any drug (absent a Constitutional amendment...which no wise person would support).
Gingrich took the position while in Congress that drug dealers should be executed.
Gingrich was a corrupt @ss. Just like G.W. Bush, and everyone in his Administration.
No person who takes an OATH to follow the Constitution, and then violates that oath, is worth even a bucket of warm spit.
