But is Donald Trump really more popular than Taylor Swift?
While Trump has a hardcore fanbase who will no doubt be supporting his 2024 presidential campaign, Swift is one of the most popular celebrities in the world right now with her record-breaking Eras Tour.
In 2018, Swift spoke about her political views for the first time in her career when she endorsed two Democrats - Phil Bredesen, candidate for Senate, and Jim Cooper for the US House - in her home state of Tennessee for the midterm elections.
Trump, who was president at the time, responded by declaring that he liked Swift’s music “about 25 per cent less”.
Swift's concerts and Trump's rallies are the places where their supporters get to connect with them in person and are key to maintaining their influence and interest.
Swift has sold out stadiums with her Eras and according to QuestionPro data, the average attendance per show was 72,459, accounting for closed-off areas and floor seats, as a result, it is the highest-grossing concert tour of all time.
There has been much debate surrounding the number of attendees at Trump's rallies as Trump himself has claimed "thousands of people get sent away" from his rallies due to popular demand.
But a report from DCReport's David Cay Johnson estimated there were under 1,500 at the Waco rally, from the images gathered.
While DCReport previously referred to a 2022 Orlando Sentinel article that reported a venue with a listed capacity of 8,700, Trump fans bought only 5,406 tickets which increased to 6,200 after giving away seats which meant 30 per cent of seats remained empty.

It's difficult to get a conclusive overall figure for the money made by Swift and Trump from their merchandise sales, but some of their recent merch sales have recently made headlines.
From her Eras Tour concerts alone, it is estimated Swift made $200 million from the sale of t-shirts, sweatshirts, and other items emblazoned with her name and logo, according to Forbes.
Trump made over $7 million in sales, from t-shirts to the “Never Surrender” coffee mugs with his infamous mugshot, in the first week after he was indicted in the Georgia election interference case, Politico reported.
