Major recent polls suggest that former Vice President Joe Biden will defeat President Donald Trump by a decisive margin in next week's election.

But for the obsessive poll watchers who in 2016 were shocked by Trump's win, today's numbers are fraught. We'll talk about how election polls are constructed, how to interpret them and how methodologies have changed since 2016.
