The first thing that's wrong about this is the assumption that the most economically disenfranchised vote at all. The least financially secure voters have some of the lowest turnout in America, with only about 20% of them voting [1]. These people fundamentally don't vote. The second problem is to try to pretend like Trump actually has a claim on the working class as his base to a greater extent than other candidates. He doesn't [2]. The median income on Trump supporters from the primaries was higher than that of Clinton supporters or Bernie supporters. He also claims a larger take of the wealthiest voters, who compose 9% of his voters in the primary, vs. Clinton and Sanders' 7% and 5% respectively. Fundamentally, his demographic skews more wealthy than the democrats.
A recent gallop survey with a large sample size shows that Trump's base don't live in areas that experience job loss due to companies moving overseas, nor do they live in areas with large immigrant populations [3]. They live in areas that are largely racially segregated (largely white). They have tradecraft jobs like HVAC repairmen, plumber, etc. and live relatively comfortably. Fundamentally though, these people have low exposure to people of color, which might explain their bigotry. Finally, surveys tend to show that Trump voters have a more negative opinion of muslims and people of color [4], which should be of no surprise.
So no, please pedal your "Trump's voters are the economically anxious white workers of America" narrative somewhere else. The truth is that Trump voters are bigots.
