Even with the electoral system, this is wrong. When a policy issue comes up, politicians look at their constituency. An issue may be very important to certain demographics, but if those demos don't vote, they don't care. One of the single best ways to get your voice heard is to vote. Even if it doesn't have direct impacts, it drastically changes what politicians look at. They won't vote to your every whim just because if it, but they'll try to gain your vote at any opportunity they can. Lots of small decisions add up.
