Hillary Clinton and the two other Democratic candidates for president said in Sunday night's debate that national security doesn't make any of their top priority lists.

The three candidates were asked what their top three priorities would be if elected president, and ignored national security despite growing fears that terrorist might slip into the United States, and that the country might be pulled into a long-term war overseas.

Sen. Bernie Sanders, I-Vt., who is running as a Democrat, said his priorities would be healthcare for everyone, a $15 minimum wage, and creating new jobs through infrastructure spending.

Clinton named economic issues like jobs and equal pay for women, building on Obamacare, and finding ways to unite the country and end the "mean-spiritedness" seen in the last several years.

Former Maryland Gov. Martin O'Malley listed higher wages and letting illegal immigrants work, climate change, and a "new agenda" for U.S. cities.
