This is why organizing is important. You, I and others have stated how important it is to reach out to non voters. Getting 5 to 10% of non voters to participate can have huge ramifications on elections. This strategy has to be used at the local/state level. It can be much more attainable for left leaning progressive candidates to win a local election than state. Usually garnering 2000 to 3000 votes can win a local race like city council or alderperson.
