Before or after watching this 6 min. video clip, see our schematic of the Socialist History in America. Note the neo-conservative cadre (see R/H margin) with us today was spawned by the Far Left. Learn to recognize them in the Republican Party. Gingrich, Romney, and Santorum are ALL neocons, internationalists, and subversive of our American heritage. Their masters are the CFR and corporate cabalists.
It is my educated estimate that the neocon influence in the GOP became apparent in the Eisenhower Administration. Eisenhower was a favorite of Eleanor Roosevelt. (more below) This association lends weight to Gingrich's admiration of FDR.
