It's not just mob rule that people worry about, but the rapidly-changing passions of the masses. It's not just that the mob is ruling that is the problem, but also how quickly public opinion can change on some things, which can lead to uncertainty about what the laws will be. New Hampshire has so many representatives and has elections so often that we're practically a direct democracy, and we've just swung back-and-forth rapidly between a liberal, progressive legislature, an ultra-conservative teabagger legislature, and now back to a more reasonable liberal legislature, and most of the time they've spent just undoing the legislation passed by the previous legislature. Having such rapid shifts in the law is no way to govern.
