"Presidential elections effects on pop culture "

Now I know it's just a notion eventhough it's been the case with presidential elections in the past,but it does seem that for whatever reason a presidential election is always followed by either a major shift in pop culture or just a shift in general.Examples where this seem to be the case in recent memory is in 2001,2008,2016 and 2020 and if you go further back than that you could say 1981 as well.
