Negativity drove me out of politics in the mid-Nineties.

It's just madness. First email. Then instant message. Then MySpace. Then Facebook. Then LinkedIn. Then Twitter. It's not enough anymore to 'Just do it.' Now we have to tell everyone we are doing it, when we are doing it, where we are doing it and why we are doing it.

Democracy is but an experiment in the long history of the world.

Mitt Romney is a businessman, a turnaround artist, a CEO. That is who he is. The former governor has experience in the public and private sector.

Outside events can change a presidential campaign, a president, and the history of the nation: the Iranian hostage crisis, the bombing of the Marine barracks in Beirut, the downing of the helicopter in Mogadishu, Somalia, the suicide attack on the USS Cole, and, of course, the terrorist attacks of Sept. 11, 2001.

Presidents should do whatever possible and practical to encourage an environment of cooperation and bipartisanship. And they should maintain a certain level of decorum, diplomacy and decency. But, at the end of the day, presidents get elected to enact change.

Mention the name George W. Bush in mixed company, and you're likely to spark a lot of debate and emotion - hot and cold, good and bad. Not a lot of neutral reaction. He was elected in the most controversial contest in American electoral history and governed during one of the most tumultuous decades.
