If 5% is enough for a political party to gain minority party status, it should be enough to get into the debates.
@asxshadowsxfade :
I think it's more about TV Time....There's only 90mins...With the top two by polls, that's possibly 45mins each....With 4 candidates, each would get 22mins 30seconds...Now, if they divided up the time by poll percents, it would look like this: Clinton would get 40mins, Trump would have 37mins, Johnson would get 9 mins, and Stein would enjoy 4 mins...
So the question is, do you want to hear more from the candidates most likely to actually be your next President? I'm sure Donald and Hillary would both love to have 8 people up there, that's less heat on them...
