Who to trust?
New England Journal of Medicine
The New England Journal of Medicine for the first time in 208 years steps into politics with an editorial signed by all of the journal’s editors:
With no good options to combat a novel pathogen, countries were forced to make hard choices about how to respond. Here in the United States, our leaders have failed that test. They have taken a crisis and turned it into a tragedy.
When it comes to the response to the largest public health crisis of our time, our current political leaders have demonstrated that they are dangerously incompetent. We should not abet them and enable the deaths of thousands more Americans by allowing them to keep their jobs.
This follows Scientific America endorsing someone for President for the first time in it’s 187 years:
The evidence and the science show that Donald Trump has badly damaged the U.S. and its people—because he rejects evidence and science. The most devastating example is his dishonest and inept response to the COVID-19 pandemic, which cost more than 190,000 Americans their lives by the middle of September. He has also attacked environmental protections, medical care, and the researchers and public science agencies that help this country prepare for its greatest challenges. That is why we urge you to vote for Joe Biden, who is offering fact-based plans to protect our health, our economy and the environment.
