Lyin' Ted will state at his next appearance: "Donald Trump has NO Foreign Policy advisers", as he's done when Donald says, "I support the Second Amendment", and next day Cruz will say, "Donald Trump will end the 2nd amendment". Or when Donald says, "I will repeal Obamacare," next day Cruz says, "Donald Trump supports Obamacare!" and so forth. And that's why he will be forever known as Lyin' Ted.
In political science textbooks, when you look up "liar", you'll get the page about Lyin' Ted.
