I was just pointing out that if you add up your numbers, they’re higher than the number of those who actually vote in presidential elections. You get 60% to 80% of the population of eligible voters, but that’s not the relevant population. Only around half of that population actually votes. Given the swing voters, that means something less than a quarter of the total population consistently votes for either major party.
The studies Vox cites in the article weren’t done by them. They’re cited all over the place, which is why it’s common knowledge now that race played a bigger factor than economic resentment. Here’s a bunch more studies: here, here, here, here, here, and here. If it’s liberal sources that are reporting these studies, that’s of no consequence since conservative ones are anti-intellectual and wouldn’t want to shoot themselves in the foot by proving they were swayed by Trump’s savagery (his racism, sexism, etc).
Democrats voted for Obama because they wanted “change.” “Change” was the mantra: change especially from the incompetence of Bush Jr. It wasn’t because they thought dark-skinned people are superior to whites. They didn’t vote based on racism, the belief that one race is superior to another. So your argument about 2008 and 2012 is specious.
Why would you “guess” the claim about Trump’s making race an issue in 2016 is based on anything to do with a nonracial aspect of illegal immigration? Trump’s racist comments and actions during and before that campaign are well known. See, for example, the long Wikipedia article on the subject, which goes into his comments on the Hispanic judge, the Somali refugees, and so on. Don’t forget his trolling on Obama’s citizenship, since that alone makes the case.
By the way, I’m not American so I won’t be voting in US elections.
