George Washington, Andrew Jackson, William Henry Harrison, Zachary Taylor, Ulysses Grant, Rutherford Hayes, James Garfield, Benjamin Harrison, Theodore Roosevelt and Dwight Eisenhower all rode their wartime heroics into the White House.

Something about her eyes or voice has always suggested the hint of a free spirit, trapped in a Peck and Peck cage, dreaming of making rude noises at public gatherings of Republicans.

These people have served a longer sentence than some people who have committed murder.

Traditionally, marriage is one arena where states have all but plenary power; it took until 1967 for the Supreme Court to tell states they could not prohibit interracial marriage.

Somebody is going to have to do fancy footwork to make sure Elizabeth and John Edwards get their prime-time shot .

For millions, Roger Ebert will be remembered as a writer and television personality who brought a sense of passion and excellence to his craft. For me, he is a man who fused joy and courage as few others ever have. My life was enriched by having such a friend; it is poorer for losing such a friend.

History doesn't turn on a dime; it turns on a plugged nickel.

As a personal matter, I stopped voting more than a decade ago, on the grounds that it helped me as an analyst not to think about making a choice in the voting booth.

If the court strikes down the Defense of Marriage Act, is that a 'liberal' result enabling gay couples married in states where gay marriage is legal to enjoy the same economic advantages that federal laws now grant to straight couples? Or is it a 'conservative' ruling, limiting the federal government's ability to override state power?

When I listen to the complaints that follow just about every presidential debate, I'm reminded of the well-worn joke about the Jewish mother who buys her son two shirts. When he shows up at dinner wearing one, she says: 'What's the matter? You didn't like the other one?'

In every debate, whatever the format, whatever the questions, there is one and only one way to identify the winner: Who commands the room? Who drives the narrative? Who is in charge?

When an office-holder facing a multi-count indictment says that he has decided to spend more time with his family, the proper response is a horse-laugh. When an accused politician explains that a charge of corruption is 'really' an attack on his or her race, religion, ethnic background or gender, the odds that something felonious happened jumps.

When the blood of thousands of Americans is shed, the impact lingers. For a generation after the Civil War, the Republican injunction to 'vote as you shot' kept the party dominant for decades; from 1868 to 1912, only one Democrat - Grover Cleveland - won the White House.

The charge that liberal candidates don't connect with or understand the values and beliefs of regular Americans is embedded in old epithets like 'limousine liberal,' which I first heard aimed at New York Mayor John Lindsay in 1969.

When George W. Bush picked Dick Cheney, it was a reassuring sign that the Texas governor would have an experienced, prudent voice at his side.

Men and women in my lifetime have died fighting for the right to vote: people like James Chaney, Andrew Goodman and Michael Schwerner, who were murdered while registering black voters in Mississippi in 1964, and Viola Liuzzo, who was murdered by the Ku Klux Klan in 1965 during the Selma march for voting rights.

It strikes me as a sound, honest statement for a prospective voter to say: 'Look, I haven't given this election a minute's thought, and it's just not fair for me to cancel out the vote of someone who actually gives a damn.' Indeed, it's not just sound and honest - it's the ethically responsible thing to do.

In another life, before taking the veil of journalistic purity, I practiced the black arts of a political operative, including 'debate prep.'

So you wake up this morning and find you're president of the United States. Pretty cool, no? Helicopters and a 747 at your disposal; courtside seats at any NBA playoff game of your choice; everyone stands up and the band plays when you come into the room.

In the many-mansioned house of Alternate History, I occupy a small corner. The trio of what-ifs I chronicled in 'Then Everything Changed' all begin with tiny, highly plausible twists of fate that lead to hugely consequential shifts in history.

In early 1961 a new president, John F. Kennedy, was told by military leaders and civilian officials that the Kingdom of Laos - of no conceivable strategic importance to the U.S. - required the presence of American troops and perhaps even tactical nuclear weapons. Why? Because if Laos fell, Asia would go red from Thailand to Indonesia.

I got into television because I hated it so. I thought, there's some way of using this fabulous instrument to be of nurture to those who would watch and listen.

There are good people who are dealt a bad hand by fate, and bad people who live long, comfortable, privileged lives. A small twist of fate can save or end a life; random chance is a permanent, powerful player in each of our lives, and in human history as well.

F.D.R. had to deal with Southern segregationists - and outright racists - who held power in Congress, so he had to yield to that power in order to get his New Deal legislation passed.

In the post-Watergate atmosphere of 1975 and 1976, the just-plain-folks personalities of both Ford and Carter seemed the perfect antidote to Nixon's arrogant, isolated presidency. But as alert history-minded readers know, Ford and Carter were both rebuffed by voters in their efforts to hold on to the presidency.
