“In 2020, as a percentage of the electorate, 18-29 year-olds cast only 11% of the total vote. In 2016, they were 21% of the electorate. This data suggests that young people are not showing up at the same rate during this election cycle.”
Or, being young people, they’re putting it off until Election Day.
Today's 18-year olds were 14 years old in 2016. The public schools and culture in general have done nothing in the last four years to turn children into responsible adults.
Most 18-year olds will probably not vote. They will be too busy buying new clothes and cutting them to pieces with knives or razors.
