There's a lot of Americans who have been propagandized into thinking that good things are actually bad and bad things are actually good. That, and the higher-paid workers and business owners who have a material connection to this ideology, and who are disproportionately represented in the voting population.
They're probably fishing for people they can galvanize. I'm not sure how many people take the spirit of contrarianism against these things to the polls, rather than just staying home and distrusting the political system further.
