A "pretender" to a title of power is a person laying a potentially valid claim to the title. The United States currently has a different kind of "pretender" as their president, in the sense that Donald Trump is merely faking it, in every possible way. He never had the capability to be the President for real, and with his rapidly progressing case of brain rot, he isn't even keeping up appearances.
It should now be obvious even to the gullible fools who were tricked into voting for him that the United States' highest office is occupied by a senile criminal narcissist without any governing skills whatsoever. Donald Trump is a pathetic joke of a person, elected illegitimately by Russian meddling, and he is not even trying to do the job.
