As first lady, Hillary Rodham Clinton jaw-boned the authoritarian president of Uzbekistan to leave his car and shake hands with people. She argued with the Czech prime minister about democracy. She cajoled Roman Catholic and Protestant women to talk to one another in Northern Ireland. She traveled to 79 countries in total, little of it leisure; one meeting with mutilated Rwandan refugees so unsettled her that she threw up afterward.

But during those two terms in the White House, Mrs. Clinton did not hold a security clearance. She did not attend National Security Council meetings. She was not given a copy of the president’s daily intelligence briefing. She did not assert herself on the crises in Somalia, Haiti and Rwanda.

And during one of President Bill Clinton’s major tests on terrorism, whether to bomb Afghanistan and Sudan in 1998, Mrs. Clinton was barely speaking to her husband, let alone advising him, as the Lewinsky scandal sizzled.

In seeking the Democratic presidential nomination, Mrs. Clinton lays claim to two traits nearly every day: strength and experience. But as the junior senator from New York, she has few significant legislative accomplishments to her name. She has cast herself, instead, as a first lady like no other: a full partner to her husband in his administration, and, she says, all the stronger and more experienced for her “eight years with a front-row seat on history.”
