The Washington Roundtable: Susan B. Glasser and Jane Mayer speak with Sarah Longwell, a longtime G.O.P. strategist and publisher of the Bulwark. Longwell has conducted focus groups across the country for the past eight years, and her research provides an unparalleled look at what motivates certain Republican voters to stay with Trump and what causes others to abandon him. She’s applying that research to persuade a segment of Republican voters to change their vote to Biden, now that Trump has become a convicted felon. What can Democrats learn from her efforts, and from the Republican Party’s messaging tactics?This week’s reading: “Fighting Trump on the Beaches,” by Susan.
