The 9-9-9 plan would resuscitate this economy because it replaces the outdated tax code that allows politicians to pick winners and losers, and to provide favors in the form of tax breaks, special exemptions and loopholes. It simplifies the code dramatically: 9% business flat tax, 9% personal flat tax, 9% sales tax.

It is wise to keep in mind that no success or failure is necessarily final. Success is not the key to happiness. Happiness is the key to success. If you love what you are doing, you will be successful.

All of the major accomplishments that I have made in my career have been in many instances against the odds.

Just call me Mr. Cain. And in 2013, they can call me Mr. President.

I honestly believe that there's an element in this country in our politics that does not want to see a businessman succeed at getting the nomination for the Republican Party and does not want me to succeed at becoming President of the United States of America.

This whole notion that all African-Americans are not going to vote for Obama is not necessarily true. I believe a third would vote for me, based on my own anecdotal feedback. Not vote for me because I'm black but because of my policies.

Donald Trump has been about we, the people. I just wanted to counter that sound bite because that's part of the problem, bad sound bites. He's been about we the people. If he were just about Donald Trump, you wouldn't have had 14 million people voting for him.
