Some Americans are already voting for their next president and, if polls are to be believed, the economy and immigration are at the forefront of many of their minds.
Voters consistently favour Donald Trump over Kamala Harris as the best person to manage both, but recently Harris has narrowed the gap.
The economy
In a Kaiser Family Foundation (KFF) poll from early September, Trump held a 15-point lead on the economy. However, more recent polling has shown a narrower single-digit lead.
For many people, though, the economy comes down to one simple factor: purchasing power – particularly, what they can afford in their day-to-day lives. Essentially, the difference between what they earn and the rate at which prices are increasing, or inflation.
Real-terms wages were higher under Trump, with average earnings consistently outpacing inflation.
This was especially true during the pandemic, as average earnings were boosted by the departure of lower-paid employees from the workforce.
Overall, during his presidency, real wages increased by 7%.
Since Joe Biden and Harris have been running the economy, real wage growth hasn’t been as strong.
By mid-2022, it had fallen nearly 4% below where it had been at the start of their term.
Much of this was affected by the post-COVID recovery and external factors driving inflation.
There are signs that the economy is now improving for ordinary Americans, with real wage growth only 1% lower than when Biden and Harris took office.
But what is important to the candidates’ electoral success is whether voters are noticing the difference.
And it’s not yet clear that they are.
“Economists are saying ‘Unemployment has fallen, the economy’s growing stronger, so is wage growth’, which is true. But some people feel worse off now,” says Shaun Bowler, a professor of political science at the University of California Riverside.
Petrol (or ‘gas’ as it’s called in the US) prices are a good example.
In America, more than nine in 10 households own at least one vehicle.
During Trump’s presidency, petrol prices remained relatively low, staying under $3 per gallon and even dipping below $2 during the pandemic.
By contrast, under Biden and Harris, petrol prices rose to $3.06 per gallon by June 2021, hitting nearly $5 a year later.
Much of this was driven by factors outside of their control, including the global energy crisis following Russia’s invasion of Ukraine.
This trend wasn’t unique to the US. In the UK, the cost of unleaded petrol rose by two-fifths from £1.30 per litre in June 2021 to £1.84 a year later.
“The Trump administration inherited a good economy from (Barack) Obama, one with low unemployment and inflation and that persisted for a couple of years,” says Professor Bowler.
“Then COVID upset everything, followed by the big supply shock of the war in Ukraine which gives us high inflation,” he adds.
While petrol prices have since dropped to $3.39 per gallon in the US, they remain higher than at any point during Trump’s term.
It’s these cost of living issues which have encouraged the Harris campaign to talk about what she would do as president to help the middle class, rather than spend too long trying to defend Biden’s economic record.
Immigration
One part of Biden’s record that Harris can’t escape is immigration, not least because the president tasked her with tackling the root causes of migration from Central American countries.
Trump has called Harris Biden’s “border tsar” and sought to blame her for problems at the US-Mexico border, and immigration policy overall.
She has been famously criticised by Trump for not visiting the border much during the last four years.
The vice president made her way there last week for a campaign rally. She was selling a message of zero tolerance on illegal immigration and highlighting an improvement in the data.

But polls have consistently suggested that voters have little confidence in her record on the issue and still favour Trump as the candidate to manage it. Why?
Trump’s rhetoric has been more hardline, marked by the promise of a border wall which was never built during his victorious 2016 campaign for the presidency.

One of the things Trump did introduce was Title 42 – a public health order during the pandemic – which enabled authorities to swiftly expel migrants without offering them the chance to seek asylum.
This led to an initial drop in people trying to cross the border between the official points of entry, but implementation was challenging.
Some countries were more able than others to accept people removed under Title 42. This meant the policy didn’t have as much impact as intended.
Nevertheless, these illegal crossings were relatively low, compared to when they rose during Harris’s first years in post.
This led to her having a bad reputation for handling the border.
But in recent months, there’s been a sudden and significant fall in people crossing between points of entry, most likely driven by a policy change.
In June, Biden and Harris introduced a controversial asylum ban allowing the deportation or turning back of migrants if illegal crossings exceed 2,500 per day for a week.
In the first month alone, illegal crossings dropped from 83,536 to 56,399.
However, it’s difficult to predict whether this will continue.
“After any sort of big policy change, we often see a drop in migrant encounters. It becomes this wait-and-see period and previously we’ve seen numbers go back up,” says Colleen Putzel-Kavanaugh, associate policy analyst at the Migration Policy Institute.
In contrast, the number of undocumented migrants attempting to enter the US through official crossing points remains high.
This shift is largely due to the expanded use of an app called CBP One which in May 2023 became the only way migrants could schedule appointments for asylum claims at the border.
As with the economy, though, Harris has been narrowing the gap in the polls on immigration since taking over at the top of the Democratic ticket from Biden.
But this is still an issue Trump leads on with most voters.
Abortion rights
While Harris is making some progress in improving her standing versus Trump on the fundamental issues of the economy and immigration, she’s also trying to raise the profile of abortion as an election vote winner.
Abortion is one of the most divisive issues in the US and Harris has made it a cornerstone of her campaign.
She has polled well on the issue, with a strong 19-point lead in a recent survey from KFF, and there’s evidence she is mobilising support among women.
“It’s been a winning issue for Democrats since the overturn of Roe, it is going to be playing out in various states on the ballot in November, and the Republicans basically don’t have a coherent line,” says Dr Richard Johnson, senior lecturer in US politics and policy at Queen Mary, University of London.
Trump’s appointment of judges that secured the conservative majority in the Supreme Court during his presidency helped in overturning Roe v Wade in 2022, allowing states to decide their own abortion laws.
Since then, several states have effectively banned most abortions, forcing women to travel across state lines for care.
From 2019 to 2023, the number of women who sought an abortion in a different state grew by 133% from more than 73,000 to over 170,000.
This November changes to abortion laws are on the ballot in 10 states and at least two of these, Arizona and Nevada, are key battleground contests.
As the race nears its final stretch, Trump’s reputation for handling key issues like the economy and immigration remains strong in the polls, but Harris has worked hard to close those gaps, while also boosting the profile of abortion as a pivotal issue.
The question now is whether voters will trust Trump’s version of his past performance or be swayed by Harris’s vision for the future.
