there will be meaningful change if Trump wins the election
True.
I can also guarantee that voting won’t be enough to prevent that. Hillary won the popular vote by nearly 3 million votes in 2016, and still lost the election. When the DNC is determined to lose an election through strategic incompetence, they’ll do it regardless of what we do at the ballot box.
Voting isn’t entirely pointless, and we should do it if we are able, but it isn’t the silver bullet that liberals always pretend it is when they’re haranguing leftists online.
