I think that a direct democracy is only workable at a small local level because in big places, there are too many people and a direct democracy cannot take place-
a direct democracy is when yu talk directly about wat yu think and yu express yer opinion that way;
in a smallest local level,every-ones opinion can be heard but it isn't possible when there are too many people; not every-ones opinion will be able to be heard..
so overall; there are too many ppl at the state and national levels to hear every-ones opinion, there needs to be few people to have a direct democracy.
