First: "My vote won't count." Well out of millions of votes for a president or governor, maybe you can feel that way. But at the other end of the scale, when voting for dog-catcher or soil and water conservation district supervisor, or even city councilor, there are elections that are won and lost on 24, 13, or even one vote. Clearly it is much harder to think your vote does not count in these situations. So, vote yourself and get out the vote (GOTV).
Second: talk with your family, friends, and even with the folks in the grocery check out line. Ask them when and where they plan to vote. Get them to think specifically how and when they are going to vote. This kind of conversation helps turn out the vote.
