I'd bet farmers would much rather have repeat customers or the promise of future valuable repeat customers over bailouts. But with these tariffs and retaliations, their former buyers are finding new sources. Even after the trade war ends, inertia will be another hurdle for our farmers.
Maybe they should not vote for guy who did exactly this already once and said repeatedly that he will do this.
Frankly, they voted for Trump, because they thought only liberals, trans and other people they hate will be harmed. It is really not the case that they would be victims on an unexpected event. They wanted this to happen, just kind of to everyone else.
US farming already has extremely high levels of government intervention aimed at price stability. This leads to all sorts of things like the government paying some farmers not to grow crops, some farmers being prevented from selling their crops, farmers getting paid after a bad season, government minimum price guarantees, and so on. And the overwhelming majority (like 95%+) of all produce in the US is sold by farmers to commodity markets, at more or less fixed rates, who then process/distribute it.
