'm trying to look beyond the propaganda, any idea if there has been scientific studies or anything remotely credible ?
I'm afraid this is the problem - your implication is that Trump voters need explaining using scientific analysis as some sort of aberration.
One day, there will hopefully be an analysis - but it will be of how among huge parts of the media and establishment this ideological view became the null hypothesis to the extent that people - in good faith - thought they were looking beyond the propoganda while asking questions like yours.
