Well, there are 2,080 hits on YouTube for “Ted Cruz eats booger” but I’m not so deeply involved in the matter as to dredge through them all to find what you’re requesting.

Whatever it was, although 99.9999% likely a food particle, it clearly did not come from his nose or had shot across the stage from somewhere else. It simply worked its way out of his mouth. Strange how a supposed conservative would hate a guy like Ted Cruz so much.
