In what way is it 'tabloid phenomenon' when they are reporting on words that have been directly said by the man himself? He's said degrading things about women, including groping them - this could be indicative of his and his parties attitude to women during his Presidency. That's important.
He's made derogatory comments about Muslims, Mexicans, and accused the black President of being non-American born, presumably on no other basis than the colour of his skin. Thus, that could affect policy towards minorities. That's important.
If Trump can come up with consistent, workable policies that he looks like he might even think about sticking to, then they'll be discussed. They are being discussed, too: his plan to build a wall continues to receive rightful scrutiny.
Trump may be President-elect but the stances towards his bigotry and hatred should not be reduced compared to what it was pre-election - he remains the man he was then, and it should be the duty of the American press to hold him to account for his actions.
