At the debate, Donald Trump backed off of his health care position for 20 years. For 20 years, he has agreed with Hillary Clinton and Bernie Sanders on socialized medicine, saying Obamacare doesn't go far enough. He wants the government to pay for everyone's health care and to control it.

We need a president who understands the first obligation of the commander-in-chief is to keep America safe. If I am elected president, we will hunt down and kill the terrorists. We will utterly destroy ISIS.
