During my 2004 presidential campaign, I was fond of saying that it was high time for the Christian right to meet the right Christians.

I work really long hours and work a lot and have done press tours and junkets, but there is nothing like a presidential campaign that I have experienced before... I think at one point we visited three different cities in one state in 12 hours. It's exhausting.

In September 2008 - as Lehman Brothers filed for bankruptcy and AIG, the world's biggest insurance company, accepted a federal bailout - Senator John McCain of Arizona, in what was widely viewed as a political move, suspended his presidential campaign and called on Obama to rush back to Washington for a bipartisan meeting at the White House.

The first-in-the-nation Iowa caucus is crucial for every presidential campaign.

As a former presidential campaign manager, I remember the final week of the campaign as being the longest and most important week of the campaign. The week doesn't seem to end.

Any time you get into a presidential campaign and the stakes are so high, all candidates - they want to be in complete control whenever they can. And you can't blame them for that.

It can be easy and tempting, especially during a presidential campaign, to listen only to opinions that mirror and fortify one's own. That's not ideal, because it eliminates learning and makes it impossible for people to understand what they dismiss as 'the other side.'

I can imagine people in Third World countries looking at, you know, someone like Hillary Clinton raising $35 million for her presidential campaign that goes to really, you know, nonproductive means, and they see that, and they just - it's just really immoral, I believe.
