The corporate media wants Trump back in the White House. They can't actually say that, but they do. The "journalists" want to go back to ragebait headlines from the president 3-4 times a day, and the oligarchs that own them want tax cuts and deregulation.
Biden's every slip up was a sign of dementia and catastrophic, while they sanewash and maybe "have concerns" about Trump's obvious decline. Treating Trump's antics seriously and allowing him to control the news cycle was at the top of every list of mistakes made in 2016. They're doing it this time on purpose.
