Apparently there are voters who vote for Trump but won't say that they will. The existence of these voters is hotly debated, with some left press saying they're a "mirage" and center and right publications saying they exist. The ridiculous hyperbole of the 4th article below aside, it seems some people vote for Trump without wanting to admit that.
Do you know any? Will they turn out for congressional elections or only him? Are they still supporters?
