Ms. Martinchek, this is a weak essay; it’s reads more like wishful thinking than objective analysis. As you know, I favor Ms. Warren’s candidacy, so I’m certainly not anti-progressive. But my highest priority is defeating Mr. Trump, and that will not be accomplished by wishful thinking. We need evidence, not hopes. The polls say that Mr. Biden is still the preferred candidate among primary voters. Please don’t deny to yourself that firmly established fact. His lead narrowed considerably after the first debates, and I am hopeful that, as the debates continue and voters learn more about the candidates, we’ll see Mr. Biden lose his lead and either Ms. Warren, Ms. Harris, or Mr. Sanders take the lead. I’m going to keep my feet firmly planted on the ground, because this election is the most important one in my lifetime, and it is absolutely crucial that we get this one right.
