Do Scientific American really think that Biden is more important than Lincoln? Or why else would they say that they refused to endorse Lincoln but now endorse Biden? I can understand them endorsing Biden, but saying "First time in 175 years" just makes it ridiculous. This election is not nearly as important or divise as the 1860 election. Edit: My point is that 175 years ago the paper was run by other people. So to me it seems more likely that the people at this paper got more and more political over time until now that they fully endorse one candidate. It is fine to endorse one candidate, but talking as if this is a once in 175 year election is not honest.
