Short answer: No.

Long answer: no, but there is some correlation between the average attention span dropping, people enjoying short form videos, and a lack of a mind for nuance which is exploited by right wing propagandists and populists, causing a rise in right wing or even far right authoritarian politicians being elected across the world. I’m not nearly educated enough in the field to make any causation claims though (edit: except the one about propaganda exploiting a lack of nuance which causes those far right politicians to be elected, that one doesn’t need a whole lot of expertise to confirm).
Also the US has always been a country of two conservative parties, which could have something to do with more people being susceptible to right wing propaganda

Most Americans think that “liberal” is someone on the left, while most European nations (as well as what little political theory I had) place them somewhere in the center, usually fiscally progressive but socially conservative.
