The generation gap in American politics is dividing two younger age groups, Millennials and Generation X, from the two older groups, Baby Boomers and the Silent Generation. In 2016, as in recent years, Millennials and Gen Xers were the most Democratic generations. And both groups had relatively large – and growing – shares of liberal Democrats: 27% of Millennials and 21% of Gen Xers identified as liberal Democrats or Democratic-leaning independents.
