The youth are generally more progressive. Recently, every demographic has displayed an increase in right-wing participation. This isn't so much of an age issue as it is a reactionary issue to educational and economic shortcomings from the last couple decades. Many right-wing populists are just really good at reaching people with distorted messaging, unfortunately.

Since many people won't read the article: it shows that there is no significant difference between the growth of the far left and the growth of the far right among young voters.

Young people are radicalizing, but the average remains to the left of older people's average. There are many young people are moving right, but there as many young people moving right too.
