Answer:
Both parties' electoral cores are made up of two comparable but separate groupings, with a youthful, more philosophically diverse population giving vital ā though not always constant ā support.
Almost a quarter of Liberals (32%) identify as Solid Liberals, while roughly a fifth (21%) identify as members of the Faith as well as Family Left, a little more culturally orthodox grouping than Solid Progressives. Throw in the Next Generation Left (18%), a younger, more economically moderate group, and you have 7 and out ten Americans who affiliate with or lean towards its Democrats.
