Don't be silly. That's just arguing about dictionary definitions. There are clear definitions what a liberal democracy is with or without your electors, and USA fits the bill neatly. Democracy is an attitude more than anything else. US citizens feel empowered, (obviously) and can make changes by having opinions. That's the key.
Whether or not it's turning so******t is another matter. The workers can vote in USA, which I guess can be argued is the dictatorship of the proletariat...but then again that would make any western country so******t...so I'm not sure. You need to work on your definitions.
