I've seen how the issues that come across a president's desk are always the hard ones - the problems where no amount of data or numbers will get you to the right answer.

I've seen firsthand that being president doesn't change who you are. It reveals who you are.

We need someone with superb judgement in their own right because, yes, a president can hire the best advisors on Earth, but I guarantee you this: Five advisors will give five different opinions. And it is the president - and the president alone - who always makes the final call.

Our greatness has always come from people who expect nothing and take nothing for granted - folks who work hard for what they have, then reach back and help others after them.

I come here tonight as a sister, blessed with a brother who is my mentor, my protector and my lifelong friend. And I come here as a wife who loves my husband and believes he will be an extraordinary president.

Whether you come from a council estate or a country estate, your success will be determined by your own confidence and fortitude.
