This article is meant to provide a relatively comprehensive assessment of Klobuchar’s strengths and weaknesses — rather than being either a “devil’s advocate” argument or a best-case scenario. It’s informed by conversations with Klobuchar’s campaign as well as with unaffiliated Democrats, but the opinions and analysis are my own. As you’ll see, I think Klobuchar’s upsides outweigh her downsides, but there’s plenty of material in both columns.Nate Silver
