That sounds like an awefully low bar, especially with the current administration, e.g. it currently score as 64th in the freedom of press index [0].
I think the people making those "established measures" are just measuring what they think makes a good government and then calling that Democracy.
Modern democracy is based on the separation of powers and, in the vast majority of countries, a constitution or charter(s) that can't be overturned by a simple majority vote. For example, a party can't suspend Habeas Corpus on a whim, even if said party won the presidency, the Congress and the Senate.
But just ask the Supreme Court who carved an exception for the FED and not other government agencies...
