No, they’re upset over a single issue every election year. They’re easily manipulated. That’s it.
This happens every four years. Like clock work. They find some hot button social issue and use it to hold our election ransom.
And also, If they thought their votes don’t matter, they wouldn’t threaten to not vote at all or vote third party if they don’t get their way. Because if their votes didn’t matter- it would be empty threats.
