In looking through my 1914 Webster’s New International Dictionary, I came across this definition as a subhead under democratic:

Democratic party, one of the two great political parties in 1828 in the United States, succeeding the Antifederalists, or Republican, party, of which it had formed one wing under the name of the Democratic Republicans. It has advocated a strict construction of the Constitution, sharp limitations on the power of the federal government, and a broad construction of the reserved rights of the States. It has generally pronounced in favor of a low tariff, practically for revenue only.

You certainly would be hard put to find any of today’s Democrats, or even very many Republicans, who could be properly included under this definition.
