Oddly enough: "Reaganomics" only achieved the limited successes it "did' due to the (generalized) belief (held by enough of the American public at that time) that the President was still "Believable" and wouldn't lie TOO BADLY to the American Public about SERIOUS issues at hand.
But now: We have grown up... THEN we saw the "Bush Administration's SOP... The overall CREDIBILITY of the "Office of the President of the United States" is all BUT nonexistent.
No pubic perception of credibility = NOTHING GWB could ever say would be regarded as anything more the "Hot Air" by MOST of America's Voters = ANY WILD DREAM of an economic policy based upon "Reaganomics" goes to show WITHOUT DOUBT how very out-of-touch with REALITY the "Republicans" actually ARE!!!
Predisposed & DOOMED to FAIL MISERABLY long before it even got a chance to get off the ground.
