Not "bizarre" at all; saying that just shows how out-of-touch MSM is.
Trump's base is mostly the same as AOC's and Bernie's: working class people who hate the status quo and want change. Only difference is Bernie and AOC's change is for the positive because they blame the correct people — corporations and the capitalist class — while Trump's change will be for the negative because he scapegoats marginalized people instead. And we know which one of them will receive corporate funding and thus come to power under a liberal "democracy"
If socialist parties like the PSL or FRSO were influential enough, most of Trump's supporters (and Dems) would be there instead. Because at the end of the day, most people are workers with the same interests.
