The demographic changes are generational as well as racial. In 2018, for the first time, millennials will surpass baby boomers as the largest cohort eligible to vote. The most recent U.S. Census data show that more than 44 percent of millennials in the country are minorities and that more minorities are born each year than non-Hispanic whites. These millennials are the most anti-Republican and anti-Trump of any voter group due in large part to their views on social issues. In addition to embracing a progressive agenda on virtually every social issue, millennials are particularly energized by issues such as energy and the environment, which they prioritize at the voting booth.
At the same time this generational shift unfolds, Democrats are increasingly self-selecting where they live and whom they choose to live near. President Trump carried 84 percent of U.S. counties, but the remaining areas, located largely on the coasts as well as urban areas in the middle of the country, voted overwhelmingly for Clinton. As much of the country moved to the right to elect Trump, the geographic areas that voted for Clinton moved further to the left. This shift is leading to the election of more progressive political leaders in the Democratic Party as these strongholds have become the political frontlines in the war against Trump.
