Propaganda is in modern times a development of the left-wing. Starting most prominently with the National Socialist Democrats in Germany of the 1930s. Socialist, communist, fascist, all are considered to be from the left-wing.Trump on the other hand is clearly not a politician and neither Republican nor Democrat. It does not appear that Trump has any ideological leanings except what appears to be free-market capitalism.
In the United States there are vast sources of information. Government control is considered anti-American and abhorrent to most people. It's a highly competitive environment with few barriers to entry other than a computer and access to the internet. The United States is 180 degrees different than Russia today. Many people apparently knows little to nothing about political propaganda. Even less about Trump. I make no observation as to Putin. As an opinion piece, it falls into the category of fake or bias news. Basically it may be reasonably said that this opinion piece is little more than propaganda for the left-wing agenda.
