> Users 18-49 were 73% of the user base and produced 72% of tweets, but only 27% of political tweets.

> Users 50+ were only 26% of the user base and produced only 28% of tweets, but 73% of political tweets.

By these numbers, users 15-17 are <1% of the user base and produce 0% of political tweets. (And even more dramatically, despite being more than 0% of users, they also produce 0% of tweets.) Even after allowing for rounding, this can't possibly be correct.

I calculated the percentages for two groups from a chart of four groups, so maybe there's more possible rounding error than you anticipated? The user base numbers in that chart do only add up to 99%, though.

Looking at the graphic in the article, it looks like their denominator is "all tweets from US adults". In other words, users 15-17 make 0% of "tweets" by definition. But of course, they are well over 0% of tweets in the ordinary sense.

I see no particular reason why tweets from 18-year-olds are especially more interesting than tweets from 17-year-olds.
