Those who have been paying close attention might note some tantalizing parallels in the politics of the United States and the United Kingdom.

In 2016, the passage of the Brexit referendum in the U.K. and the election of Donald Trump in the U.S. both involved appeals to nationalism and right-wing populism and promised greater restrictions on immigration.

While both political movements were supported most strongly by older and less well educated voters, they also helped generate a counter-reaction of activism and participation in 2017 among the mostly younger voters, who saw their preferred choice lose the year before.

In the weeks leading up to the 2017 U.K. general parliamentary election, SurveyMonkey s tracking polling revealed the enormous differences in voter preferences by age.

In our post-election survey, Labour ran ahead of the Conservatives by a better than three-to-one margin (61 to 20 percent) among voters between the ages of 18 and 24, while voters over 65 preferred the Conservatives by a nearly identical margin (62 to 20 percent).
