| While these national polls are a useful guide as to how popular a candidate is across the country as a whole, they're not necessarily an accurate way to predict the result of the election. | While these national polls are a useful guide as to how popular a candidate is across the country as a whole, they're not necessarily an accurate way to predict the result of the election. |
| That's because the US uses an electoral college system, in which each state is given a number of votes roughly in line with the size of its population. A total of 538 electoral college votes are up for grabs, so a candidate needs to hit 270 to win. | That's because the US uses an electoral college system, in which each state is given a number of votes roughly in line with the size of its population.

| There are 50 states in the US but because most of them nearly always vote for the same party, in reality there are just a handful 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 or swing states. | There are 50 states in the US but because most of them nearly always vote for the same party, in reality there are just a handful where both candidates stand a chance of winning.

| If you look at the trends since Harris joined the race, it does help highlight some differences between the states - but it’s important to note that there are fewer state polls than national polls so we have less data to go on and every poll has a margin of error that means the numbers could be higher or lower. | If you look at the trends since Harris joined the race, it does help highlight some differences between the states - but it’s important to note that there are fewer state polls than national polls so we have less data to go on and every poll has a margin of error that means the numbers could be higher or lower. |
| In Arizona, Georgia and North Carolina, the lead has changed hands a few times since the start of August but Trump has had a small lead for a few weeks now. It’s a similar story in Nevada but with Harris the candidate who has been slightly ahead. | In Arizona, Georgia and North Carolina, the lead has changed hands a few times since the start of August but Trump has had a small lead for a few weeks now.

| In the three other states - Michigan, Pennsylvania and Wisconsin - Harris has been leading since the start of August, sometimes by two or three points, but in recent days the polls have tightened significantly and Trump now has a very small lead in Pennsylvania. | In the three other states - Michigan, Pennsylvania and Wisconsin - Harris has been leading since the start of August, sometimes by two or three points, but in recent days the polls have tightened significantly and Trump now has a very small lead in Pennsylvania. |
| All three of those states had been Democratic strongholds before Trump turned them red on his path to winning the presidency in 2016. Biden retook them in 2020 and if Harris can do the same then she will be on course to win the election. | All three of those states had been Democratic strongholds before Trump turned them red on his path to winning the presidency in 2016.

| In a sign of how the race has changed since Harris became the Democratic nominee, on the day that Biden quit the race he was trailing Trump by nearly five percentage points on average in the seven swing states. | In a sign of how the race has changed since Harris became the Democratic nominee, on the day that Biden quit the race he was trailing Trump by nearly five percentage points on average in the seven swing states. |
| In Pennsylvania, Biden was behind by nearly 4.5 percentage points when he dropped out, as the chart below shows. It is a key state for both campaigns as it has the highest number of electoral votes of the seven and therefore winning it makes it easier to reach the 270 votes needed. | In Pennsylvania, Biden was behind by nearly 4.5 percentage points when he dropped out, as the chart below shows.
