Campaigns often make standing on principle the highest of virtues - and listening to your opponents a sure sign of weakness. It's the virtual opposite of what it takes to succeed in office. Squaring the circle takes a powerful combination of skills. But presidents who can campaign and compromise are generally the most successful.

Bill Clinton sitting on Air Force One getting his hair cut while people around the country cooled their heels and waited for him, became a metaphor for a populist president who had gotten drunk with the perks of his own power and was sort of, you know, not sensitive to what people wanted.

The first time I met Bill Clinton was actually 1988.

Obama seemed poised to realign American politics after his stunning 2008 victory. But the economy remains worse than even the administration's worst-case scenarios, and the long legislative battles over health care reform, financial services reform and the national debt and deficit have taken their toll. Obama no longer looks invincible.

When I first started working in politics, as a junior aide on Walter Mondale's 1984 presidential campaign, it never occurred to me that I would one day work in the White House. There were plenty of women among the volunteers who stuffed envelopes and walked precincts. But there were fewer and fewer on each successive level of influence and access.

You as the press secretary have to protect the president's interests and the White House's interests more broadly. And a lot of people inside the White House, as you learned, sometimes with painful experience, have competing agendas, have differing points of view, have priorities they're trying to protect.

While eschewing emotion - and its companion, vulnerability - Obama should be careful not to sacrifice empathy, the 'I feel your pain' connection that sustained Clinton. This connection is the shorthand people use to measure their leaders' intentions. If people believe you're on their side, they will trust your decisions.
