As a reactionary, I've got no particular love of democracy, particularly of the unlimited suffrage model. However, I can't reasonably say: Absolutely Nothing.
Democracy actually is good at something.
Under many conditions in a nation that has undergone an industrial revolution and the attending revolution in military technology leading to the feasibility of mass conscripted armies, it has one thing going for it.
A vote is usually adequately predicts the outcome if a revolution were held on the subject. Hence the losing side does not have the reasonable expectation that they can do better through resort to arms. This doesn't mean they won't resort to arms, because after all, the will is at least as important as raw power in warfare, but it makes it much less likely, making the system more stable.
However, what happens when you extend the franchise such that military power becomes out of balance with effective political power (in this I'm not speaking of raw votes in an election, but rather the ability for a group to have its way or promote its interests)? It should be pretty clear that military power density in the US is considerably out of alignment with political power density---clearly the political power of the US resides not with rural white males. This takes from democracy its only real virtue and promises interesting times ahead, in the Chinese accursed sense.
