I really believe that there are going to be a lot of arguments to make against him that we can look forward to, I'm not going to spill the beans right now. But, suffice it to say that there are many arguments that we can use against him. But, one argument that I am uniquely qualified to bring, because of my service as Secretary of State is what his presidency would mean to our country and our standing in the world. I am already receiving messages from leaders - I'm having foreign leaders ask if they can endorse me to stop Donald Trump.
