Interesting. How many voted in this poll for Duncan Hunter? I did, for one. Why didn’t our votes register?
They are showing the poll results in whole numbers. Therefore a candidate’s percentage of support has to reach at least the number one.
DH apparently had fewer than 1% of responders support him. So instead of expressing his support as a decimal less than one, the result was simply shown as a “ - “ -— a dash meaning “something less than 1%.”
