Two things stood out for me tonight. First, the night's sharpest and most effective attacks on Trump focused on how Trump's coronavirus response cost lives. Kristin Urquiza and New York Gov. Andrew Cuomo were extremely effective at this. Second, Democrats made strong overtures to Black voters with speeches like Michelle Obama's and the powerful moment of silence led by George Floyd's brothers. They know that low Black turnout is a big reason why they lost in 2016.
