Julius Caesar, the Great Democrat, was an emperor. So were the democrats called “Caesar”, such as the German Kaisers and the Russian Czars, and those who simply emulated Caesar and his democratic ambitions.
In this country, the chief democratic ambition is to be President, to be the Emperor of the Earth, to hold the oxymoronic title of “Leader of the Free World”. Democratic political machines such as the DNC and the RNC have to remind their “down ballot” candidates that “serving” in Congress and holding state and local office is a pathway to the Presidency. They are perturbed when a Jacksonian democrat like Mr. Trump grabs the main prize without “paying their dues” but in the case of the RNC — with its Conservative Democratic RINOs who regularly attend Conservative conferences rather than Republican clubs — they are willing to forego their discomfort at such rudeness if it will build their farm system of petit democrats. Similarly, the DNC is less concerned with the fate of the country and its people than they are with getting their Emperor installed.
We have had a few Presidents who were incapacitated — Wilson with his stroke, Reagan with his Alzheimer's — without the country collapsing. The people were not imperiled, but the empire was. The problem is not that a candidate for emperor is parading around with an empty head but that we have or seek an emperor at all.
