This article by Tiffanie Turnbull & Jason Arnesto is published by the British Broadcasting Corporation (BBC). Here is an excerpt:
When Americans went to the polls for the last midterm election, they did so in unusually high numbers. Unusual, that is, by American standards.
According to the US Elections Project, 50% of the voting-eligible population cast a ballot in 2018, the highest midterm turnout since 1980.
With close contests and high interest nationwide, Americans may beat that 2018 mark this cycle. Even so, it would pale in comparison to voter participation levels recorded in other democratic nations.
