Happy Tuesday! Venerated pollster Mark Penn explains how one sentence in one book he read for a Harvard class influenced his entire career. That sentence? "Voters are not fools," from The Responsible Electorate, by V.O. Key, Jr. Perhaps, Penn argues, it's the "elites" as a whole who are the fools. Also on today's menu: Taylor Swift, Winston Churchill, and Penn's new book, Microtrends Squared.
