Who will win the presidential election? Our experts predict the race

In our latest analysis instalment, Telegraph writers reflect on the week since the television debate and an new assassination attempt

The question on everybody’s lips – who is going to win the election on Nov 5?
There are now less than 50 days to go until polling day. Since our election swingometer was last updated, Kamala Harris has received a boost in the national polls after her performance in the television debate, and Donald Trump faced a second assassination attempt while golfing in West Palm Beach. 
However, the polls also show that most voters have already decided which way they will vote in this election, and there has been little change to the vital swing states and counties that will actually decide this race. Our experts’ average shows they feel Ms Harris is narrowly more likely to win the election, but it remains too close to call.
Our writers have been predicting the overall winner of the election since early this year, periodically plotting their choices on a sliding scale of likelihood. 
After this week’s events, they have now updated their predictions below.
Kamala Harris may have the better deck as things stand, but this race remains perilously difficult to call. The vice-president remains narrowly ahead in reputable national polls, but the White House will turn on seven states where the margins between Ms Harris and Donald Trump are down to decimal points. 
Pollsters have also noted that with a fast-paced news cycle – Trump’s second assassination attempt came just as they were conducting post-debate surveys – there are logistical challenges to determining which events are swaying voters. 
Trump insiders have shrugged off the polls, and some see echoes of 2016, when the ex-president confounded the pundits. As one GOP strategist told me: “I think you could make a strong case now where you could have a different winner in the electoral college to the popular vote.”  
One week on since Kamala Harris’s victory in the first – and possibly last – televised debate, the polling gap has barely shifted. 
Nationally, Ms Harris leads by just three points, an increase from two points depending which polls you look at.  A second assassination attempt against Trump could help close it once again, but as with other “defining” moments of the election, any gains seem to be quickly reversed. 
Polling shifts are even lower in the seven swing states, which will decide the election. Currently though, polls suggests this election could come down to just one state: Pennsylvania. Here, Ms Harris leads by 0.2 points, a gap so statistically insignificant, it is impossible to say who is really ahead. 
This election is still very much neck and neck. 
Polls indicate a slight improvement for Kamala Harris since the debate, though liberals over-excited by the evening forget that Trump has never performed well in them (except vs Biden at his most senile). It seems Ms Harris is gaining in the swing-states too, though Trump maintains a large lead among the cats and dogs of Springfield, Ohio.
It’s intriguing to note that both media and public seem unmoved by the multiple attempts to kill the Republican candidate. So, the race gently tilts Democratic – but it all depends on how wrong the polls are and in what direction. If they’re out like they were in 2020, Trump is on the road to victory. If they’re out like they were in 2022, Ms Harris is even stronger than she appears. 
Perhaps we shouldn’t be surprised that the second assassination attempt on Donald Trump’s life has hardly seemed to shift the agenda this week. As the race hurdles to a close and the news cycle speeds up, even attempts at murder can only command the headlines for a matter of days. Even Springfield, Ohio – currently caught in the eye of the culture war storm – feels mostly forgotten.
Supporters of Kamala Harris will likely feel positive about their position less than two months to election day. With a host of celebrity endorsements, bursting campaign warchest, and a well-received performance at the debate, some liberal commentators have taken to declaring the race over. 
Still, there’s an undeniable whiff of 2016 in the air. Battleground polling is still fiercely competitive, with Pennsylvania’s swing measured in the tenths of a percentage point. There’s little hard evidence that Ms Harris’s “wins” have translated to potential votes – with an electorate this polarised, it’s hard to imagine what a real October surprise would have to look like to move the dial.
Kamala Harris is enjoying a run of good press after her debate performance last week, and she has also benefitted from a series of unforced errors from the Trump campaign – not least a confrontation between his staff and officials at Arlington Cemetery and apparent divisions between Donald Trump and JD Vance, his running mate. 
The second assassination attempt against Trump will have fuelled the narrative that he is under attack from many enemies, but I wouldn’t expect that to make a major difference to the polls now. Both candidates are fighting over a very small proportion of undecided voters, and this has become a race of very fine margins. 
Our experts are asked to plot their decision on a scale of 100, where 0 is a Harris landslide, 50 is a tie and 100 is a Trump landslide.
