They're assuming (probably correctly) that a lot of people under 28 won't vote, and that (probably less correctly) they'd vote Democrat if they did vote. So if Trump wins and they pass a random 28 year old on the street, they're thinking there's a good chance that person is partially responsible for Trump's win.
under the age of 28 ?
It makes extra sense because it includes ages 0-17
I am still lost

Appreciate the clarification
Ok that makes more sense thanks. 28 seemed very arbitrary but if the statistics say so...
