"This book is written for those who, being new to the ballot, wish fo do their part to make politics good instead of bad, but who find themselves puzzled at the outset by the unfamiliar face it wears... It is not a handbook for voters, telling them where their assembly districts are and how to mark a ballot... These pages aim to answer the simple and yet fundamental questions that arise the minute a new voter begins to ask himself what he can do with his vote...

"But the immediate occasion of its publication is the enfranchising of the women of New York... for the coming of New York into the woman suffrage ranks is obviously the beginning of the end. Since, therefore, the women of New York constitute a large class of those new voters for whose needs it is intended, a considerable amount of space is given to political questions that arise in New York, and to the state laws of New York governing voting..."
