You do recall the Trump admin had to bailout farmers last time don't you? Is that "fact" a "fact" to you? If the 2018 Trump trade war had no negative effect on farmers, then why the need to bail them out? Here's an article from 2019 where the source is
the Trump USDA:
WASHINGTON (Reuters) - The U.S. Department of Agriculture expects the value of U.S. farm exports to drop by $1.9 billion to $141.5 billion in fiscal 2019 from a year earlier, led by a steep decline in shipments to China due to an ongoing trade dispute, a department official said on Thursday.
The forecast was issued even as trade negotiators from the world's two largest economies were working ahead of a March 1 deadline to resolve their trade spat, something that could vastly change the USDA's outlook, if successful.
"The share of total U.S. agricultural exports to China in value terms is projected to be 6 percent, down sharply, with China falling from the top market in 2017 to fifth place," USDA Chief Economist Robert Johansson told the USDA annual forum in Washington.
He said the United States had exported 24 million metric tonnes of soybeans in the 2019 crop year, down 13.5 million metric tonnes from this time last year.
"Under the trade dispute, exports to China alone have plummeted by 22 million tonnes, or over 90 percent," he said.
The Trump USDA expectation is exactly what the Biden USDA noted. I find the amount of mental gymnastics here amazing.
