Agreed. The number one priority is to get people off their arses and vote.
The other thing we could do is try and learn how and why voter apathy is so disproportionally beneficial to fascists. If we can get a percentage of apathetic voters to get up and vote, that's a great start, but is there anything we can do to reduce the damage from the remaining non-voters? For example, Ireland's PR-STV system seems a good way to weed out polarised voting behaviours.
