How did the pollsters get the U.S. presidential election so wrong?

Hi.

In part because they were lying and in part because they were dreaming of a liberal victory. They based their partial reliable and unreliable polls on the fact they knew the US has changed his values, not overwhelmingly but in a number that is so great that now seems to be a half of the country, so they were really convinced that the millennials (the generation Z) was going to be their triumph card but thanks to the Catholic Church call to its faifhful sons this didn't happen and roughly won by delegates because by popular vote she would be the president right now, which is a serious indicator that the US is rapidly becoming a huge liberal nation and threatens to win future elections and change life as we traditionally knew.

The other factor of incidence in their unreliable statistics was the money coming from Clinton, Comey hesitatingly admited that she lied about all what is was in her emails, among the worst things was the bribery of public and private institutions, especially the media and rioters. The more the money flowed to the media the more their polls looked exaggerated compared to impartial ones in the US and worldwide and those made by Trump.

Most pollsters are biased, and most are biased towards Dems. They'd survey twice as many Democrats and Republicans, they'd look to take polls in Democrat-heavy areas, and report Clinton winning.

They would say online polls weren't trustworthy when Trump kept winning them. Anytime Trump won a poll, it was dismissed as being biased and inaccurate.

This discourages the 'losing' party's voters, kills their spirit, can result in low voter turnout, etc. So there's actually a political advantage to looking like you're winning in the polls.

Rasmussen usually shows Reps winning whether they are or not, they've been employing this tactic for a while. This year, most mainstream liberal media sources like CNN and MSNBC did it with Clinton.

The only polls that consistently showed the race neck-and-neck was Fox.

Only LATimes, a relatively new poll, had Trump up all along. They have a unique and balanced way of polling. Last election their results were most accurate. This election as well.

At realclearpolitics.com "The final RCP Four-Way National Poll Average showed Hillary Clinton winning the popular vote by 3.3 points. "

The error was about 2 points then.

The state polls averages had about the same error as in 2012.

It was a close election with a lot more undecided or 3rd party voters than usual, she had some serious electoral college weaknesses, and as Tmess2 pointed out, the media didn't interpret polls well, for the most part. A lot of political veterans blew it too.

For the most part, they didn't. Media outlets covering the polls failed to understand what polls mean. The final average of the polls was showing that Clinton would win the popular vote by about 4%. While we do not yet have a final count in the popular vote, based on the outstanding votes in California, Secretary Clinton will probably have a final popular vote win of around 1.5%. A two percent error in the popular vote is close to the typical error in most election cycles.

Most oversampled democrats. Had they used samples that were proportional to reality, then they would have obtained different results. Also, polls don't factor in voter turnout. Many may have preferred Hillary over Donald but that doesn't mean they would vote for Hillary. Most accurate polls had the race close. Some polls like the IBD/TIPP poll had trump winning.

They didn't account for Democrats that secretly intended to vote Trump. Same with blacks and Hispanics that would not admit they weren't liberal. With all the insults and hate against Republicans, lots of people said they would vote Democrat but did not intend to really do that.

Alex Jones had it right and he said the globalists were lying

Liberalism is a disease that causes people to lose their ability to be correct about anything.

I tell you what they're all idiots.
