The US is very dysfunctional for anyone but the upper middle class. We all see our taxes taken out of our check, and the services provided to us are very limited: no working healthcare system, limited affordable housing, abusive elder care industry, few social safety nets, student debt & cost of education, etc.
One party (Republicans) is convinced the government is broken (it has lots of problems) and their solution is to... break it more. They throw a lot of red meat to their voters (hatred toward minorities, LGBTQ+) to keep them energized and distracted. They also seem to be literal fascists lately, and are breaking our voting systems through pushing misinformation to make people distrust our institutions.
The other party (Democrats) ignores their progressive supporters and pushes milquetoast half-meassures to solve problems. They are weak, inept. However, they aren't interested in literally erasing LGBTQ+ people or marginalizing racial minorities. Nor are they interested in breaking our democratic processes.
Corporate-owned media has been pouring gasoline on this trash fire the whole time. I hate people who do this whole "both sides" shtick (Because the parties are not the same, it's fascism vs a party that still seems to believe in democracy), but that's what I think of when I see things like this . This is an article about how right wing talking heads are pushing some conspiracy about Taylor Swift and the Super Bowl, and it appeals to that part of my brain who wants to laugh at dumb people who disagree with me. But I have to point out, nobody actually cares.
People are lonely and bored and are making how they vote into rooting for some sort of sports team. You can see it in the replies to your post: someone called the right wing a "cult". I'd like to say there is some grand conspiracy where corporations are dividing the working class but the truth is probably far more bland: Rage gets clicks, and this is dividing us. It's not hard to do because the USA is a very flawed place with a lot of wealth inequity.
