People really did not like Trump they just didn't like incumbents more.
It's almost like if the Democrats ran a competitive primary this whole situation could've been avoided.
In 2016 Trump got 63M votes. Clinton got 66M.
In 2020 Trump got 74M votes. Biden got 81M.
In 2024 Trump got 77M votes. Harris got 75M.
Trump's popularity increased with each election. Turnout for Harris was definitely lower than the previous election, but the dip was not exceptional. Trump won because of his popularity - not despite it.
Take a look at other world wide elections that happened in 2024.
Like France (parliamentary system so no presidential election); The incumbents lost 33% of their seats [1].
Or UK; The incumbents lost 67% of their seats [2]
And yet, Trump didn't even make it to 50% of US votes. People really did not like him. People really hated incumbents. Your numbers even show this, Biden 1 has more votes than Trump 2; they just didn't support the incumbent anymore.
