Why is everyone studiously ignoring the proverbial "elephant in the room"??? The concept of an "Imperial" or all-powerful emperor-like presidency has certainly been kicking about since the Truman era... Nixon obviously thought that he could get away with just about anything, and that "If the president does it, it's not illegal", but he was sacked for being crude and blatent about it and making a collosal blunder in the Watergate affair. That said, the full flowering of the Imperial or "Unitary" presidency was achieved under the Bush Jr. regime. "Dubya" acted very much like an emperor - starting and controlling wars with minimal congressional permission and oversight, making hundreds of bills democratically passed by congress and the senate effective null and void anytime he wished to circumvent or ignore them, through the often questionably legal devise called a "signing statement", which enabled him to ignore any law he "signed away" any time he wished, and appropriating many of the traditional powers of congress to himself...... look up "Emperor Bush" (or "Emperor Cheney", since that particular vice president had far more power and influence than the traditional role of the vice president) for more info. Recall that the Bush man famously said "I am the Decider", and "One of the best parts about this job is that i don't have to explain my decisions" :-+). The constitution drastically limits the power of the president, except in times of war and extreme emergency (and no, the "war on terror" doesn't really count: 9-11 was an isolated incident, not a reign of terror - a one of a kind event that the neo-cons exploited to grasp powers that the constitution did not give or permit them.). The Bush presidency basically said: to heck with the constitution, I am the Decider, i don';t have to explain anything, and i'll do whatever i like - and anyone who has a different viewpoint is a traitor and can go to hell. THAT is what the "Imperial Presidency" was all about in practice. // As to how it happened, i think that congress mainly let it happen by not challenging the president any time he overstepped his constitutional bounds. Fear was a big factor: those that wished the president to be more powerful than the founding fathers prescribed, have consistantly used the most effective methods of most who wish to attain and then hold on to the most power possible - fear, misinformation, appeals to pride and patriotism, threats against those who dare to disagree...
