Every person over the age of 12 in the US knows who Trump is. Few people under the age of 35 in the US know who Taylor Swift is. The majority of adults in the world know who Trump is. Whether they think he’s good, are indifferent or think he’s the antichrist is irrelevant to whether they know who he is. He was a US President. Before that he was on TV for decades. He’s literally been on TV via the news, daytime shows, late night shows, comedy shows, everyone had an opinion and was talking about him. Taylor Swift isn’t on TV every day. Or even every week. Trump is currently running for President again. Like him hate him or don’t care about him, most people know him.
