Benjamin Disraeli shared these thoughts on establishing democracies:
If you establish a democracy, you must in due time reap the fruits of a democracy. You will in due season have great impatience of the public burdens, combined in due season with great increase of the public expenditure. You will in due season have wars entered into from passion and not from reason; and you will in due season submit to peace ignominiously sought and ignominiously obtained, which will diminish your authority and perhaps endanger your independence. You will in due season find your property is less valuable, and your freedom less complete.
Jerry Pournelle adds this:
Government by public opinion poll is about the same as plebiscitary democracy. America was established as a Republic. The States could have democracy if they so chose. The Federal government had not that power and for good reasons, the Framers in 1787 having already known what Disraeli tried to tell Parliament some fifty years later.
