Generational differences have long been a factor in U.S. politics. These divisions are now as wide as they have been in decades, with the potential to shape politics well into the future.

From immigration and race to foreign policy and the scope of government, two younger generations, Millennials and Gen Xers, stand apart from the two older cohorts, Baby Boomers and Silents. And on many issues, Millennials continue to have a distinct – and increasingly liberal – outlook.

These differences are reflected in generations’ political preferences. First-year job approval ratings for Donald Trump and his predecessor, Barack Obama, differ markedly across generations. By contrast, there were only slight differences in views of George W. Bush and Bill Clinton during their respective first years in office.
