Somewhere along the line, the Republican Party became merely the nameplate for the radical right in this country.
The radical right is, in fact, a coalition of those who fear other Americans: as agents of treason, as agents of confiscatory government, as agents of immorality.
This fear gives the modern Republican Party its well-noted cohesiveness and its equally well-noted practice of jugular politics.
Even in power, the modern Republican Party feels itself to be surrounded by hostility: beginning with government itself, which they present as an enemy; extending to those in the opposition party; and ultimately, on to that portion of the country whose views and hopes are represented by it -- that is to say, to virtually half the nation.
Under these circumstances, it is natural -- perhaps tragic in the classical sense -- but nonetheless natural -- for the modern Republican Party to be especially proficient in the use of fear as a technique for obtaining and holding power.
This phenomenon was clear under both Presidents Reagan and Bush Sr., except softened to an extent by the personalities of both men.
Under our current President Bush, however, the machinery of fear is right out in the open, operating at full throttle.
Fear and anxiety have always been a part of life and always will be.
Fear is ubiquitous and universal, in every human society, a normal part of the human condition.
But we have always defined progress by our success in managing through our fears.
Christopher Columbus, Lewis and Clark, the Wright Brothers, and Neil Armstrong -- all found success by challenging the unknown and overcoming fear with courage and a keen sense of proportion that helped them overcome real fears without being distracted by distorted and illusory fears.
As with individuals, nations succeed or fail -- and define their essential character -- by the way they challenge the unknown and cope with fear.
And much depends upon the quality of their leadership.
If their leaders exploit their fears and use them to herd people in directions they might not otherwise choose, then fear itself can quickly become a self- perpetuating and freewheeling force that drains national will and weakens national character, diverting attention from real threats deserving of healthy and appropriate concern, and sowing confusion about the essential choices that every nation must constantly make about its future.
Leadership means inspiring us to manage through our fears.
Demagoguery means exploiting our fears for political gain.
Fifty years ago, when the nuclear arms race with the Soviet Union was raising tensions in the world and McCarthyism was threatening freedom at home, President Eisenhower said, "Any who act as if freedom's defenses are to be found in suppression and suspicion and fear confess a doctrine that is alien to America."
But only 15 years later, when Ike's V.P., Richard Nixon, finally became president, it marked the beginning of a big change in America's politics.
Nixon embodied the spirit of "suppression and suspicion and fear" that Eisenhower denounced.
And it first became apparent in the despicable midterm election campaign of 1970 waged by Nixon and Vice President Agnew.
I saw that campaign firsthand: my father, the bravest politician I have ever known, was slandered as unpatriotic because he opposed the Vietnam War and accused of being an atheist because he opposed a Constitutional amendment to allow government-sponsored prayer in the public schools.
I was in the Army at the time -- on my way to Vietnam.
I had a leave the week of the election.
"Law and order," and court-ordered busing for racial integration of the schools, were the other big issues.
It was a sleazy campaign by Nixon -- one that is now regarded as a watershed marking a sharp decline in the tone of our national discourse.
In many ways, George W. Bush reminds me more of Nixon than any other previous president.
Like Bush, Nixon subordinated virtually every principle to his hunger for reelection.
He instituted wage and price controls with as little regard for his "conservative" principles as Bush has shown in piling up trillions of dollars of debt.
After the oil embargo of 1973, Nixon threatened a military invasion of the oil fields of the Middle East. Now Bush has actually done it.
Both kept their true intentions secret.
Like Bush, Nixon understood the political uses and misuses of fear.
After he was driven from office in disgrace, one of Nixon's confidants quoted Nixon as having told him this: "People react to fear, not love.
"They don't teach that in Sunday school, but it's true."
The night before that election, 33 years and three months ago, Sen. Ed Muskie of Maine spoke on national television for the Democrats and said, "There are only two kinds of politics. They are not radical and reactionary, or conservative and liberal. Or even Democrat and Republican. There are only the politics of fear and the politics of trust.
"One says: You are encircled by monstrous dangers. Give us power over your freedom so we may protect you.
"The other says: The world is a baffling and hazardous place, but it can be shaped to the will of men ... [C]ast your vote for trust ... in the ancient traditions of this home for freedom."
The next day my father was defeated. Defeated by the politics of fear.
But his courage in standing for principle made me so proud that I really felt he had won something more important than an election.
In his speech that night, he stood the old segregationist slogan on its head and defiantly promised: "The truth shall rise again!"
I wasn't the only person who heard that promise. Nor the only one for whom that hope still rings loud and true.
I hope and believe that this year the politics of fear will be defeated and the truth shall rise again.
Almost 3,000 years ago, Solomon warned that where there is no vision, the people perish.
But the converse is also surely true: Where there is leadership with vision and moral courage, the people will flourish and redeem Lincoln's prophesy at Gettysburg: that government of the people, by the people, and for the people shall not perish from the earth.
