Introducing The 46th, a new series from “The Argument” charting the incredibly unconventional transition from President Trump to President-elect Joe Biden. Each week through inauguration, we’ll debate what — and how — Mr. Biden should prioritize in his first 100 days. With Ross Douthat on intermittent paternity leave, Michelle Goldberg is joined by Opinion editor Aaron Retica for an interview with Congresswoman Pramila Jayapal. As the Democrats are poised to reclaim the executive branch, how should the growing divide between the party establishment and its progressive members like Representative Jayapal find common ground? Then, Kara Swisher — tech reporter and host of the NYT opinion podcast, “Sway” — joins Michelle and Aaron to discuss what social media companies are doing (or not doing) to combat misinformation and conspiracy theories surrounding the election.
