Each of us has but one vote. Yet we can all influence thousands of votes. And we should start with the people who need the least amount of urging. If you have friends who already agree with you on the key issues of the day, and who would probably support the candidates you support, please make sure that they do in fact intend to vote for that candidate. Some information from you, a friendly nudge, or perhaps a promise of assistance to get them to the polls can go a long way.
We should reach for the “low-hanging fruit.” If the same amount of energy by which we persuade one who disagrees with us can mobilize ten people who agree with us already, get the ten first; then come back for the rest.
