Donald Trump is in full meltdown mode. Could he destroy his own campaign? | Arwa Mahdawi

What do you think Donald Trump does for stress relief? Massages, maybe? Or perhaps he binge-drinks Diet Coke while bed rotting . Maybe he writes down his grievances on pieces of paper and then flushes them down the toilet . It’s also possible he lets off steam by smashing gold trinkets with his golf clubs and throwing paper towels at Puerto Ricans . That feels very on-brand.

Whatever Trump does to manage his stress, I imagine he’s doing a lot of it right now. The convicted felon has had a terrible three weeks . Ever since Joe Biden dropped out of the race, things have been going rapidly downhill for Trump. His campaign had been built around bashing Biden, whose frailty and questionable mental acuity made him an easy target. With the far more energetic and coherent Kamala Harris as his opponent, Trump clearly doesn’t know what to do. His campaign now seems to consist of nothing but racism, the revival of old grudges, conspiracy theories and insults.

This strategy isn’t exactly working out for him. A New York Times/Siena College poll published on Saturday found Harris four points ahead in the crucial battleground states of Wisconsin, Michigan and Pennsylvania. This is a big deal: when Biden was the nominee, Trump was either always slightly ahead in those states or the two men were neck and neck. It’s not just the polls that have shifted, media coverage has, too. A month ago, every headline seemed to be questioning Biden’s mental competence; now, headlines are focused on Trump’s unhinged rambling.

While Harris’s campaign has huge momentum and exudes competence, Trump is embroiled in chaos. One of the latest debacles? He was hacked . In a post on Truth Social, Trump claimed the hack was “by the Iranian Government” and added: “Never a nice thing to do!” No – but it provides a good opportunity to remind everyone that Trump’s Twitter (now X) account was compromised in 2020 by Victor Gevers who successfully guessed the password was “maga2020!” This was after the ethical hacker hacked Trump’s Twitter in 2016 by guessing the password was “yourefired”, the catchphrase from The Apprentice. The man who wants voters to think he can manage national security can’t even manage his own passwords.

Even an interview on Monday night with his pal Elon Musk was a rambling, grievance-filled disaster. It was also beset by serious technical issues, leading a Harris spokesman to quip that Trump’s campaign is in service of “self-obsessed rich guys who … cannot run a livestream in the year 2024”.

Trump isn’t dealing with his stream of setbacks very well; according to Republican sources quoted in a recent Axios report, he “is struggling to get past his anger”. The New York Times has similarly reported that a seething Trump repeatedly called Harris a “ bitch ” in private – claims that Trump has denied, despite the fact that he’s happily called the vice-president all manner of names in public. Essentially, he’s in full meltdown mode.

So, too, are Trump’s allies, who are desperately begging their candidate to get a grip and start focusing on actual issues, rather than personal attacks. Instead of heeding this advice, however, Trump seems intent on alienating the people who can help him win. At a campaign rally in Atlanta earlier this month, Trump picked a fight with Brian Kemp, Georgia’s popular Republican governor, whom he termed “little Brian” and accused of having turned Georgia into a “laughing stock”. Georgia is an important state to win and, before Biden dropped out, it seemed as though it was in the bag for Trump. Now he’s polling the same as Harris. Making an enemy of Kemp is a terrible strategy.

While it’s highly satisfying to think of a furious Trump setting his own campaign on fire, it’s important not to be complacent. As we know, things change quickly. Harris may be on the up now, but she hasn’t won this election yet. It’s also important not to underestimate the dangers a desperate Trump poses. There’s a chance he might implode, yes. But there’s also a chance he might explode , leaving a hell of a lot of collateral damage in his wake. In an interview this weekend , Biden said that, if Trump loses, he’s “not confident at all” there would be a peaceful transfer of power. Nor am I.

In case you were wondering, by the way, there is a real answer to the question about how Trump manages his stress. During a 2004 interview with Larry King, he said: “I try and tell myself it doesn’t matter. Nothing matters … That’s how I handle stress.” I wish I could give that technique a go myself. The problem is, if you’re keen on things such as bodily autonomy and democracy, then this election really does matter.
