The article where they endorsed a presidential candidate for the first time in their history was pretty atrocious too - just based on out and out lying about what the US coronavirus response involved and how it compared to the rest of the world. It turns out that when you mix science and politics, all you're left with is politics that calls itself science and accuses its political opponents of attacking science.
I respected SA for that. And I think it was on topic for them given the anti-science sentiment transpired from one of the sides. And science will always be political.
The notion is that it was extremely fast delivery of a complex solution by an administration known to regularly stretch the truth when politically convenient (if not outright lie, c.f. inauguration crowd size and, now, response to the legitimate 2020 election).
The reality is that the mRNA vaccines were basically ready to go within a few weeks, and political dregs kept it from being approved even faster. But its inadvisable to change the bureaucratic infrastructure for disasters during disasters, and so here we are.
But yes, the crowd that Trump tends to seek support from is anti-science.
At risk of feeding the troll, but the vast majority of the US population are incompetent at science. There is a reason that science is the domain of people who are not only fairly smart but also carefully trained in how to make decisions based on evidence rather than social dynamics. While Trump's appeal is targeting people who are clearly scientifically-illiterate ... all politicians have messages crafted to appeal to scientific illiterates. There aren't enough scientifically competent people to even be a meaningful swing vote.
Every partisan is perfectly happy to claim that they are following science and usually fail to modify their behavior when confronted with actual science. That holds across the political spectrum. The Trump crowd aren't anti-science, they simply tend to anti-authority. I guarantee you that they're highly pro-science on the issues where the science agrees with them.
