I think that you are parroting Hannity's total lies. Labelling Harris as "too far left" is expected from an extreme right winger!!
It is all relative. Harris is certainly not too far left were
she in Europe or even Canada. Core population in the U.S. is overall less
liberal than in the rest of the western world. Evangelical segment of the
Christians remains a formidable political force which could influence a
good portion of the population of the youth. Biden as a liberal is moderate.
It is reasonable to expect Harris a non-white woman to be unable to
capture all of the votes meant for Biden.
