A lot of people voted for the rapist felon, as I write he is in fact winning the popular vote.
This is on the people and the society they live in. It's not "the messaging" from either party - it's simply that Trump appeals to a lot of Americans, as unpalatable as that is.
IMHO people vote for Trump because he normalises the hate and jealousy that they feel themselves for their situation and their powerlessness to change it. How he projects his own narcissism makes him look like a kindred spirit to them, and the fact that over 50% of the voting American public can relate to this is a stunning indictment of US society.
That's a whole lot of mind reading and guessing of what 50% of the country thinks, it's not simple, no one is that one dimensional and different groups have different reasons
Gen Z, millenials, boomers, gen x all have slightly different social and economic goals
The fundamental christians are not the same as the homeless bernie bros and classic liberals
In 2020, a Pennsylvania white man illegally voted via mail-in ballot on behalf of two deceased parents.
Also in 2020, a black woman in Memphis voted while ineligible due to a felony conviction without being informed she wasn't allowed, and was convicted and sentenced to 6 years in jail.
As for how this applies to why Trump is not in jail for his convictions, I will leave that as an exercise for the reader.
Someone failed that women long before she voted if she didn't know a convicted felon can't vote, at least in my state they ask when you register
Just a note: a lot of people, including moderates, perceive his felony conviction (in the Stormy Daniels case) as a politically motivated prosecution engineered by his political opponents. Pushing that prosecution as far as they did almost certainly contributed to Trump's victory rather than having its intended effect of making him untouchable.
An election result wandering from 46.8% to 51% does not indicate a huge shift in American culture in general. It just looks that way because of the flaws in our political system.
Until we reckon with our true national spirit, which is Donald J. Trump, we cannot kill the movement behind him because that IS America, in a very literal sense.
