US election 2020 polls: Who is ahead - Trump or Biden?

 

Voters in America will decide on 3 November whether Donald Trump remains in the White House for another four years.

The Republican president is being challenged by Democratic Party nominee Joe Biden, who is best known as Barack Obama's vice-president but has been in US politics since the 1970s.

As election day approaches, polling companies will be trying to gauge the mood of the nation by asking voters which candidate they prefer.

We'll be keeping track of those polls here and trying to work out what they can and can't tell us about who will win the election.

Biden leading national presidential polls

National polls are a good guide as to how popular a candidate is across the country as a whole, but they're not necessarily a good way to predict the result of the election.

In 2016, for example, Hillary Clinton led in the polls and won nearly three million more votes than Donald Trump, but she still lost - that's because the US uses an electoral college system, so winning the most votes doesn't always win you the election.

With that caveat aside, Joe Biden has been ahead of Donald Trump in most national polls since the start of the year. He has hovered around 50% in recent months and has had a 10-point lead on occasions.

34 days until Election day

The BBC poll of polls looks at the  individual national polls from the last 14 days and creates  trend lines using the median value, i.e. the value in the middle of the set of numbers.

By contrast, in 2016 the polls were far less clear and just a couple of percentage points separated Mr Trump and his then-rival Hillary Clinton at several points as election day neared.

• A really simple guide to the US election
• How will early voting impact the election?

Which states will decide this election?

As Mrs Clinton discovered in 2016, the number of votes you win is less important than where you win them.

Most states nearly always vote the same way, meaning that in reality there are just a handful of states where both candidates stand a chance of winning. These are the places where the election will be won and lost and are known as battleground states.

In the electoral college system the US uses to elect its president, each state is given a number of votes based on how many members it sends to Congress - House and Senate. A total of 538 electoral college votes are up for grabs, so a candidate needs to hit 270 to win.

As the map above shows, some battleground states have a lot more electoral college votes on offer than others so candidates often spend a lot more time campaigning in them.

Who's leading in the battleground states?

At the moment, polls in the battleground states look good for Joe Biden but things can change very quickly, especially when Donald Trump's involved.

The polls suggest Mr Biden has big leads in Michigan, Pennsylvania and Wisconsin - three industrial states his Republican rival won by margins of less than 1% to clinch victory in 2016.

But it's the battleground states where Mr Trump won big in 2016 that his campaign team will be most worried about. His winning margin in Iowa, Ohio and Texas was between 8-10% back then but it's looking much closer in all three at the moment.

That's one of the reasons why some political analysts rate his chances of re-election as low as things stand. FiveThirtyEight, a political analysis website, says Mr Biden is "favoured" to win the election, while The Economist says he is "very likely" to beat Mr Trump.

Who won the presidential debates?

Donald Trump and Joe Biden went head-to-head in two live TV debates.

The first, on 29 September, was a chaotic affair, with Mr Trump's combative approach stamping out any chance of a real debate.

Polls taken straight after that suggested it was a good night for Mr Biden.

In a CBS News/YouGov poll of people in battleground states who watched the debate, 48% said Mr Biden was the winner while 41% went for Mr Trump - a similar split to the national polling averages. Nearly 70% of people said the debate made them feel "annoyed".

A snap CNN poll gave Mr Biden a larger winning margin, with 60% of people saying he had won, compared to 28% for Mr Trump.
