- gerrymandering: voting for someone that will gerrymander is once again voting for your own interests (this time at the expense of democratic values). If the prone-to-gerrymander candidate you are voting for does in fact gerrymander, it is likely to be in favor of that political party (which is the one you voted for).
- Voter ID: I think everyone who wants stronger voter ID laws and is voting for them is not particularly worried about not having an ID when it comes time to vote in the next election.
- Reducing voting stations is an interesting one, but again I think most of the people who would vote for a party that reduces voting stations are not worried about access to them (either because they can easily take time off to vote, they are quite mobile, or because they are happy with mail-in-ballots).
So I think you are helping make my point, but in the opposite direction of how you meant – those are a bunch of examples of people voting selfishly in a way that could hurt democracy. I want people that would vote for such things to vote against their own self-interest, and instead vote for what is best for the health of our democratic republic.
