Biden leads Trump, but can polls be trusted this year?

WASHINGTON, Oct 18: Donald Trump's victory in the US presidential election four years ago brought into question as never before the reliability of opinion polls. Can they be believed this time around?
- What do the polls say? -
With 16 days to go before the November 3 election, Democrat Joe Biden is ahead of the Republican president by 9.0 percentage points nationally, according to polling averages from the RealClearPolitics website.
But in the United States, candidates win the White House not through the popular vote, but with the Electoral College.
In 2016, Trump lost the popular vote to Hillary Clinton, but won enough states to garner the electoral votes needed to become president.
This year, six states are seen as key to winning the White House: Florida, North Carolina, Arizona, Wisconsin, Pennsylvania and Michigan.
But if the polls are correct, Biden also has the advantage there, although he is at times within the margin of error, ranging from 1.7 percentage points ahead in Florida to 7.2 in Michigan.

Where were the errors in 2016?
The polls on the eve of the vote correctly predicted a slight national lead for Clinton, but "the place where the polls missed were in some of those Midwestern swing states" that Trump eventually won, Chris Jackson of Ipsos Public Affairs told AFP. He said under-representation within polling samples of white residents without college degrees who voted for Trump was among the causes.
Most polling institutes say they've corrected their methodology to preclude such mistakes this time around.
Battleground states under-polled last time have been surveyed much more closely and more often.
Beyond that, pollsters note consistency: Since the spring, Biden has been ahead with an average lead which has never fallen below four percentage points.
As a comparison, the Trump-Clinton polling lines crossed twice, signalling an uncertain race. Finally, in a country extremely polarized, there are far fewer undecided voters susceptible of altering the contest at the last minute.   -AFP
