To understand the 2024 election results, it helps to go back to 2020. Donald Trump lost the election that year, but he made significant gains with nonwhite voters. At the time, a lot of Democrats saw that as a fluke, a hangover from Covid lockdown policies. But the Republican pollster Patrick Ruffini saw it as bellwether.In his 2023 book, “Party of the People: Inside the Multiracial Populist Coalition Remaking the GOP,” Ruffini argued that Trump was ushering in a party realignment. A trend that had been happening for years in the white electorate – college-educated voters moving to the left, and non-college-educated ones moving to the right – was now evident, he said, among voters of all races, breaking up the core of the Democratic base.And so far, the data we have from this election suggests that Ruffini was right.In this conversation, Ruffini, a founding partner at Echelon Insights, contextualizes the 2024 election results by looking back at 2020’s. We discuss what Democrats missed about these voter trends; the appeal of Trump’s brand of class politics; why Democrats might have been better off with a red wave in the 2022 midterms; and how Kamala Harris’s campaign may have hurt her with nonwhite working-class voters.Book Recommendations:Steadfast Democrats by Ismail K.
