John Dickerson: Some ruthnessness required

Let us now praise ruthless men. And women.

The two most talked-about potential presidential candidates in 2016 are enduring public examinations of their ruthlessness. In New Jersey, federal investigators, the legislature and the press are looking at whether Gov. Chris Christie knew aides in his office sought to punish a local official for not supporting their boss by closing portions of the George Washington Bridge. At the same time, Hillary Clinton is going through one of the periodic public checkups she has enjoyed since emerging on the national stage in 1992.

A new book, "HRC," describes a carefully tended Clinton enemies list where the couple kept track of those who had abandoned or betrayed them. The private diaries of a close confidante, first reported on by the Washington Free Beacon, describe first lady Hillary Clinton's desire to punish everyone from anonymous leakers to an Arkansas publisher during her husband's presidency.

Partisans react to these developments predictably; your opponent's penchant for ruthlessness is a sign of his or her low character. That's wrong. Ruthlessness is a necessary political skill, particularly for presidents. The task is to make an assessment about whether a particular politician uses it effectively or not. There are limits to ruthlessness - abuse of power and crippling vindictiveness - but we shouldn't mistake signs of the trait as necessary proof a politician is locked into its excesses.

In presidential campaigns some voters are uncomfortable with politicians who show an aptitude for arm-twisting. That, in turn, leads to a lot of wasted time as politicians pretend that they are not skilled in the activities required for the job that they're trying so hard to get. It gets circular fast: You deceive to prove that you are not deceptive.

Democratic strategist James Carville once famously compared Hillary Clinton with President Barack Obama by suggesting the former first lady had more guts than the president, though Carville referred to a part of the anatomy physiologically unavailable to a female candidate. Reading Diane Blair's journals, you see what Carville was talking about.

"HC still in despair that nobody in WH tough and mean enough," writes the political science professor, a longtime Arkansas friend of the Clintons, who died in 2000 and whose papers were donated to the University of Arkansas. "Most people in this town have no pain threshold," she quotes Clinton as saying in another entry. These are stories about events more than 20 years ago, but they read with potency because they offer an intimate portrait of a figure who has worked hard to shield herself from penetrating insights.

If voters are ambivalent about toughness in their politicians, they are particularly so about it in female politicians. One of the benefits of the Diane Blair documents is that they offer us a historical marker for national attitudes about women and power in the early 1990s before Clinton became the most influential American female politician of her time. "What voters find slick in Bill Clinton, they find ruthless in Hillary," reads a strategy memo in the files from the 1992 campaign. "While voters genuinely admire Hillary Clinton's intelligence and tenacity, they are uncomfortable with these traits in a woman. She needs to project a softer side - some humor, some informality."

As first lady, Clinton was a "pioneer in an anachronistic role," as Blair put it. More than 20 years later, Clinton may still have less room to appear tough than a male candidate. But the question about Clinton's toughness isn't limited to public perceptions about it. Now the question is, when does ruthlessness cross the line beyond its utilitarian benefits and into something more damaging?

Presidents need to be self-confident but not arrogant, focused but not living in a bubble, wise but not too professorial, a leader but not a tyrant. The Christie and Clinton stories offer us an opportunity to examine where ruthlessness should begin and end in the most powerful office in the land.

In New Jersey the ruthlessness of the Christie operation bled over into its abuse of power, but so far there is no connection between Christie and his aides. In the Blair documents, Clinton is ruthless in conversation in a way that we never have seen with Christie. It's gripping reading, but it's more figurative than real; Clinton couldn't abuse power because as first lady she had none. Furthermore, the machismo displayed in private conversations with a friend requires a caveat. It's possible that Clinton, powerless and under siege, talked tougher on the phone precisely because she couldn't follow through in real life.

Abuse of power is not the only downside of ruthlessness. The danger is that it can lead to an all-consuming vindictiveness. There is nothing wrong per se with an enemies list of the kind reported in "HRC." In a business of leverage and power, it's almost a best practice. Bill Clinton raised money for Sen. Claire McCaskill, D-Mo., and then she said she wouldn't let him near her daughter. She also endorsed Barack Obama in the 2008 Democratic primary. That would seem to be the kind of offense so glaring you wouldn't need a cheat sheet to remember it. But politics can get confusing. McCaskill has already endorsed Hillary for president in 2016. But there were also lesser officeholders who caused offense who occupied the enemies list spreadsheet, and in ensuing elections for attorney general and Congress, Bill Clinton campaigned in Democratic primaries against candidates who had backed Obama against his wife.

Tending to a list of enemies and ingrates can become a problem if imagining and carrying out retribution become the focus of too many hours in the day. You lose the theme of your office. Before Richard Nixon graduated to abusing power, he was consumed with his political enemies.

So if the question for Christie is whether the culture of easy retribution fostered the excesses of the George Washington Bridge scandal, the question for Clinton is whether the constant attention to allies and enemies can ever become an overwhelming distraction.
