The GOP’s Millennial problem runs deep | Pew Research Center: The relative liberalism of Millennials translates into a greater likelihood of affiliating with or leaning toward the Democratic Party compared with those in older generations. Today, about half of Millennials (50%) are Democrats or lean to the Democratic Party, while just 34% affiliate with or lean to the GOP. By comparison, Baby Boomers (those ages 50 to 68) lean slightly Democratic (46% Democratic/Democratic leaning, 42% Republican/Republican leaning), while those in the Silent generation (ages 69 to 86) are about evenly divided (47% Republican/Republican leaning, 44% Democratic/Democratic leaning).
But in addition to the generation’s Democratic tendency, Millennials who identify with the GOP are also less conservative than Republicans in other generations: Among the roughly one-third of Millennials who affiliate with or lean Republican, just 31% have a mix of political values that are right-of-center, while about half (51%) take a mix of liberal and conservative positions and 18% have consistently or mostly liberal views. Among all Republicans and Republican leaners, 53% have conservative views; in the two oldest generations, Silents and Boomers, about two-thirds are consistently or mostly conservative.
