@benroyce it's not fair to blame nonvoters when systematic vote suppression has been a major strategy of the Republican party for nearly half a century, and has been a feature of US policy since the founding. We still have many people officially disenfranchised, including people who have served their time, and many more who have been deliberately removed from voter rolls or intimidated from showing up.
Yes, there are also some people who genuinely don't care. But that too is a product of strategy and execution. We're deliberately meant to feel hopeless and disengaged. The cure isn't to condemn people for falling victim to it, but for the DNC and grassroots left to help them engage with issues in a way that gives them a reason to exercise their vote. Like, feeling empowered to change their income, their tax burden, their healthcare costs, their childcare costs, the quality of their kids' schools, the precariousness of their employment, etc. Give them reasons to take an unpaid day off work, stand on line for four hours under the armed watch of ICE "monitors", and mark their ballot. These are things worth fighting for, but the GOP has made sure that a fight it will be.
