The New Yorker has an interview with the Cook Political Report's Dave Wasserman about how the 2020 presidential race is shaping up:
The pitfalls in a potential Harris or Warren nomination are several. But the first one that comes to mind is the reinforcement of an image that the Democratic Party is dominated by coastal élitists, and, despite Warren's Oklahoma roots and populist message, her career as an Ivy League academic is a liability, or would be a serious liability in a general-election campaign. In Harris's case, Republicans would love to run against San Francisco...
Biden is no sure thing, either: "Democrats tend to underestimate the Trump campaign's ability to weaponize social media to divide the Democratic base by attacking the eventual nominee from the left. Trump's campaign, it's no secret, is going to take to Facebook ads and other media to convince casual voters—in other words, voters who only turn out occasionally—that, for example, Joe Biden mistreated women, including Anita Hill; is a creep; opposed busing; and is, generally, a corporate Democrat...I am not convinced that 2018 signals a trend toward Democrats in 2020, especially because Trump has proven he is better than anyone else at incinerating his opponents' images."
Says Wasserman, "right now I have a hard time seeing one candidate in this field who is capable of truly unifying the Democratic Party into battle. And, in fact, the Democratic field to me, so far, is more about quantity than quality."
