There's different types of young people that all don't vote.
- Those pretty well off that don't vote because they don't feel they have to and their friends don't either, community non-voting
- Those that want instant gratification, they're used to the fact that everything is a click away "I liked grandpa Bernie's Instagram why isn't my college debt gone?

" ain't nobody got time to vote when there's Fortnite loot to collect
- Those that were let down by what 'the squad' and other Dems managed to do to stop the rise of Trump or implement more progressive policies, instead they just rubber stamped his budgets and complained about Israel a lot
- Those that don't care about politics so they don't care about voting (you'd be surprised how many people think voting == politics)
In that sense, the 'owning the libs' spiel is a strong tactic of the Trump team to get people out to vote.
Even if it doesn't matter, you still owned a lib by voting and Trump does give you that instant gratification because within an hour after you voted he probably owned a lib somewhere.
If you're really lucky he might even retweet the meme you made.
I think politicians also overestimate the loyalty of those that visit their rallies. For some people those rallies are just fun and exciting events to hang out at with free loot, especially in colleges.
If you visit the artist that happens to be in town you might not go out to buy his album.
