As predicted, the House just voted, 240-179,a "resolution of disapproval" of Congressman Joe Wilson, with 12 Dems opposing, 7 Reps supporting. The Politico provided a copy of the rules he violated; you can call someone a nitwit but not a liar.
My question remains: When has a President, addressing Congress, ever accused someone in the chamber of lying, as Obama clearly did? I have been asking various scholars of the Presidency, who haven't come up with anything.
Of course FDR compared conservative Republicans to fascists in his 1944 SOU (see the sixth paragraph from the end), which puts him in an entirely different league of malefactors.
On this note consider the wise thoughts of this scholar of the presidency, on Harry Truman:
"One would be hardpressed to find a more egregious example of presidential demagoguery than Truman's remark about Thomas Dewey and the Republican party ("[T]he Republicans have joined up with this Communist-inspired Third Party to beat the Democrats") or his claim that the Republicans were the instruments of "powerful reactionary forces" intent on reducing the Bill of Rights to a "scrap of paper" (247). To make sure that his postwar audience fully grasped the horror of the situation, Truman drew parallels with Hitler's rise to power in Germany. His rhetoric infuriated the Republicans and paved the way for McCarthyism during Truman's second term."
