There are many subordinate reasons why this calamity happened and it is necessary to identify them and assign weight to them so that the important ones can be addressed and corrected.
One such reason can be addressed and could have been corrected, or at least mitigated: It is quite normal for a political party in the sixth year of the presidency to lose the Senate and House seats. In some respects, it was to be expected that this would occur now. Clinton, however, was able to resist this historical trend but those were rather special circumstances.
Similarly, history shows the political parties, after 12 years in power, tend to become arrogant, cynical, and corrupt and that certainly has happened to the Republicans in spades. The voters have just cured the arrogance dimension of this equation but it remains to be seen if the corruption has been rooted out. The "values voters" will tell us in the next election if the Republicans have abandoned their cynicism.
Other reasons are less easily identifiable and more subjective in nature. One goes to the very essence of the character of George Bush. I've long published that he is not a movement conservative, in fact he is not a conservative at all but rather he is a patrician with loyalties to family, friends, and country. His politics are animated not by conservative ideology but by a noblisse oblige which, as a substitute for political philosophy, move him to act from loyalty and love of country. The result of this is that he does not weigh his words and actions against a coherent standard grounded in conservatism, but instinctively reacts to do what is right for family, friends, and country. Thus we get Harriet Meirs, pandering to the Clintons and Kennedys, prescription drug laws, campaign finance laws, runaway spending, and the war in Iraq. The conservative movement is left muddled and confused and the Republican Party undisciplined and leaderless. In these circumstances all manner of mischief is possible beginning with corruption and indiscipline in the ranks. To be effective, a president must be feared as well is loved. A President is more than just Commander in Chief and Chief Executive of the nation, he is the titular head of his party and he must rule it. If Bush was willing to pander to the likes of Teddy Kennedy, what did Senator John McCain have to fear from him? Bush has utterly failed in his role as head wrangler of the Republican Party.
Other subjective reasons for the debacle involve Bush's personal character. He is essentially a nonconfrontational man who would rather operate through collegiality than through power. This is reinforced by his Christian belief and he will almost literally turn the other cheek. So, his loyalty to family and friends affects his appointments and produce mediocrities like Brown at FEMA and Ridge at Homeland Security and Harriet Meirs. It makes him shrink from prosecuting the crimes of his enemies even to the point of overlooking real security lapses committed by The New York Times. It makes it very difficult for Bush to discipline his troops and fire incompetent or disloyal subordinates. Instead he soothes them with the Medal of Freedom.
George Bush is a singularly inarticulate man. When he is not delivering a prepared speech, his sincerity and goodness of character come through, but his policies often die an agonizing death along with the syntax. The truth is that Bush has never been able, Ronald Reagan style, to articulate well the three or four fundamental issues which move the times in which we live. One need only cite the bootless efforts to reform Social Security as an example. His inability to tell America why we must fight in Iraq to win the greater worldwide war against terrorism, or how we are even going to win in Iraq, has been fatal to the Republicans' chances in this election. Of course, one can carry this Billy Budd characterization too far and it is easy to overemphasize its importance, but it is part of the general pattern which has led us to this pass. It is a very great pity that the bully pulpit has been squandered in the hands of a man so inarticulate. That the bully pulpit was wasted means that there are no great guiding principles for the country, for the party, for the administration, for Congress to follow, or for the voters to be inspired by. If the voters went into the booth confused about what the Republican Party stands for, the fault is primarily George Bush's.
While I appreciate your commentary, the Lord requires us to judge a personage like George W Bush and his political family by their fruit:
1. 1 million genocided Christians in Iraq since Bush’s invasion
2. Prescott Bush founded the racist, black genocide of Planned Parenthood with Margaret Sanger
3. Prescott Bush funded the Holocaust by funding Hitler.
4. George W Bush continued to fund Planned Parenthood throughout his eight years in office to the tune of billions and billions of dollars.
I shudder to think what the God of Abraham Isaac and Jacob will have to say when the Bushes stand before Him.
