The folks who vote for Linda Graham.
Cruz if right on their heels and would frankly do much better if they removed most of those names from the list who are not running and who probably will not run (like the Huckster)
I think these pollsters are purposely including this massive list to make it appear that Cruz has less support that he really has.
Make a poll that shows :Bush, Paul, Walker, and Cruz as the only candidates and you would get a completely different result.
