Why is Bob Barr not considered a big enough candidate for the presidency to be allowed in the debates?

It's not about choice and maybe they're afraid he will outshine the others and actually be honest and make sense! The bright side is that there is a growing faction of people fed up with the two major parties and something will have to give that will allow more access for other parties to have a chance to win more elections. Let's see how happy the populace is after 4 more years of Republicrat screwups!
