Republican Donald Trump's victory over Democratic Hillary Clinton on Election Day caught many pollsters off guard.
The result left Clinton supporters stunned but many Trump supporters said they never believed the polls.
For weeks, the nation's main pollsters gave Hillary Clinton a comfortable lead. So how did they get it so wrong?
"I have no idea. I don't think anybody knew what was going to happen," said Joyce Jaglowski.

Trump's stunning upset dealt a sucker punch to the polling industry, calling their mathematical models and survey methods into question.
"They've been wrong the past two or three cycles and I think the pollsters need to go back to the drawing board and figure out how they missed it this badly but again they missed it that bad four years ago in the Romney Obama race," said Pat Brady, former chairman of the Illinois Republican Party.
ABC News exit polling showed Donald Trump had a huge 39-point margin among working class whites without a college degree. Trump supporter Robert Taylor said he always knew his candidate would triumph.
"I am part of the working class and I lost a lot of my jobs due to going overseas and stuff like that and I'd like to see our business come back and make this country prosper again," he said.
ABC7 political analyst Laura Washington believes the pollsters wildly underestimated the number of hidden Trump voters.
"A lot of Trump's or people who have either never voted or don't participate heavily in elections and the way we do polling, the way we look at polling emphasizes regular voters so I think pollsters and experts just did not understand who his voters were," Washington said.
Many agree polling was one of the biggest losers of this election. But despite the faulty forecasts, some Americans are determined to move past it.
"Everybody is still trying to get into this country and there is more that unites us than separates us," said Michael Maher. null
