Millions of young Americans have graduated from college during the Obama presidency, ready to use their gifts and get moving in life. Half of them can't find the work they studied for, or any work at all. So here's the question: Without a change in leadership, why would the next four years be any different from the last four years?

I talked about the need for American leadership, I talked about the importance of the United States to a more peaceful world, a world that has been quite turbulent in recent years, and needs a strong American anchor.

It is sad that the Republican leadership is not as interested as they say they are in protecting the institution of marriage as they are in waging a campaign to divide and distract the American people from the real issues that need to be addressed.

The longer we go without strong leadership from the Administration and until we see significant progress in the day-to-day lives of the Iraqi people, the more difficult it will become to sustain the support of the American people and Congress for the current course.

The more I have studied Lincoln, the more I have followed his thought processes, the more I am convinced that he understood leadership better than any other American president.

An old African leader says about leadership, he says that leadership should never be shared; it should always remain in the hands of the dispossessed people. We will lead the revolution.

We also can't try to take over and rebuild every country that falls into crisis. That's not leadership; that's a recipe for quagmire, spilling American blood and treasure that ultimately weakens us. It's the lesson of Vietnam, of Iraq - and we should have learned it by now.

Despite the belief of many career bureaucrats that elected political leadership works for them, our system is built on the idea that the permanent bureaucracy, such as it exists, works for the elected leadership, which in turn works for and represents the American public.

I want American Dream growth - lots of new businesses, well-paying jobs, and American leadership in new industries, like clean energy and biotechnology.

Since taking office, President Obama has worked to restore a positive vision of American leadership in the world - leadership defined, not by the threats and dangers that we will oppose, but by the security, opportunity and dignity that America advances in partnership with people around the world.

House Republican leadership have refused to allow a clean minimum wage vote. Close to 15 million Americans will be affected if we did this. Do Republicans really expect a family to live on less than $11,000 a year?

American presidential leadership never goes out of style.

Leadership has become a heavy industry. Concern and interest about leadership development is no longer an American phenomenon. It is truly global. Though I will probably be in less demand, I wanted to move on.

My leadership will end the Obama era and begin a new era of American prosperity.

We need to restore U.S. leadership to a world order that is rules-based in order to protect our American dream here at home.

I chose to personally support Donald Trump for president early on and referred to him as America's blue-collar billionaire at the Republican National Convention because of his love for ordinary Americans and his kindness, generosity, and bold leadership qualities.

Globalisation means many other countries are asserting themselves and trying to take over leadership. Please don't ask Americans to let others assume the leadership of human exploration. We can do wonderful science on the Moon, and wonderful commercial things. Then we can pack up and move on to Mars.

To the best of my knowledge and of my effort, every lineage statement within 'Roots' is from either my African or American families' carefully preserved oral history, much of which I have been able conventionally to corroborate with documents.

A serious problem in America is the gap between academe and the mass media, which is our culture. Professors of humanities, with all their leftist fantasies, have little direct knowledge of American life and no impact whatever on public policy.

Part of the reason people abroad resent the United States is something Americans can do very little about: envy. The richest, most powerful country in the world attracts the jealousy of others in much the same way that the richest, most powerful man in a small town attracts the jealousy of others.

U.S. intelligence has the legal right to monitor foreign communications as they go through to U.S. service providers. However, even though something is legal doesn't make it right. I'm not American; I don't really care about what data is being collected about American citizens. I'm worried about us, the foreigners.

I believe that the Foreign Intelligence Surveillance Act must be reformed. We must improve the American public's confidence in, and perception of, our national security programs, by increasing transparency, strengthening oversight, and safeguarding civil liberties.

There is no part of the executive branch that more exists on the outer edge of executive prerogative than the American intelligence community - the intelligence community, CIA, covert action. My literal responsibility as director of CIA with regard to covert action was to inform the Congress - not to seek their approval, to inform.

We will use all lawful tools at our disposal, and that includes authorities under the renewed PATRIOT Act. We firmly believe that our intelligence gathering tools must enable us to collect the information we need to protect the American people.
