"I am seeking the Presidency because I care deeply about important issues facing America—Life, Marriage, the Fair Tax, the Second Amendment, American Border Security and Sovereignty. I am as committed to those issues as I ever was, and my campaigning around the country has convinced me that the majority of Republicans want me to continue to fight for these and other conservative causes. So I will.
I know all about the rumors swirling around. That's why I just went on national news show this afternoon, to knock those rumors down. I am still in this race. As I have said all along, I am in this race until someone gets to 1,191 delegates. That has not happened yet, and so I will keep campaigning for the Republican nomination. Period. That's my ironclad commitment to my supporters."
