How did the US news media get the presidential election so wrong?

Obviously the news media supported Hillary as her poll rating was higher than trump prior to the election.

However, we can see that US citizens place importance on integrity above all things from this election.  Trump definitely has more integrity than Hillary.

Hillary’s dubious record:

Her wealth buildup was questionable because she used her political position to gain wealth especially from using her Clinton’s foundation.

Her email scandal was questionable but was pardoned by FBI.  I must say FBI was too efficient in her investigation.  I wonder this efficiency is reserved for her only or it is across the board.

Her health was also questionable.

Last but not the least, Hillary has major trust issue in USA as close to 70% of US citizens don’t trust her and see her as a trustworthy person.  Thus, it is not surprising that she lost the election.
