So, if Hunter goes from 1% to 2% we can call it a “100% surge”?
Call it a miracle!
You would more likely be correct calling it a typo....but, yes, that would be a 100% surge.
For that to occur, the "support" for a candidate who can't win Nationally would not make any difference in the National election, even where he went from the 100,000 in Iowa that favored him, to 200,000, in that case. (Probably more like if 400 here on FR in the poll suddenly went to 800 overnight).
