The Socialists in American politics use Democratic Socialist as a label so as to disguise the real ideology they're promoting; Socialism!
Sanders during the 2016 campaign referred to a number of countries he claimed were thriving under the Socialist model. Problem was those named countries were no longer Socialist due to its miserable failure.
Meanwhile, Sanders remember has three houses and last year made 1.2 million dollars.
The Prime Minister of Denmark demanded Sanders stop with the slur when referring to his country as Socialist. Because Denmark now had a Market Economy.
And remember, Sanders, campaigning for President in 2020 honeymooned in Russia and vacationed in Cuba.
Most people don't know what Socialism is.
This is rather amusing.
