Leadership is not about a title, degree or level. Anybody can lead at any time.

The only way to reduce our national debt is to grow the economy and cut spending. We have no idea how our money is being spent. As president, I will move all agencies to zero-based budgeting so that every agency has to justify every dollar that they spend.

When our embassy is attacked in Benghazi by terrorists and there is no response, you get more bad behavior. When Russia invades Ukraine and there is no response, you get more bad behavior. When Syria crosses the red line and there is no response, you get more bad behavior. When Iran launches tests of ballistic missiles and there is no response, you get more bad behavior. When North Korea attacks Sony Pictures and there is no response, you get more bad behavior. In other words, Mrs. Clinton, you cannot lead from behind. We must respond when we are attacked or provoked.

People who have been in and around government and politics for their entire lives may no longer be able to see the truth. Our government must be fundamentally reformed. The system has to be changed. Our politics can no longer tinker on the edges.

Religious liberty must be protected in this country. It's a principle upon which we were founded.
