I found this Suffrage pamphlet there full of common sense reasons why women should vote. They have it now but are not using it.
14. Because it would help those women who need help the most. Theodore Roosevelt recommended woman suffrage in his message to the New York Legislature. On being asked why, he is reported to have answered that many women have a very hard time, working women especially, and if the ballot would help them, even a little, he was willing to see it tried. Mrs. Maud Nathan, president of the National Consumers' League, said in an address at the National Suffrage Convention in Washington, in February, 1904: "My experience in investigating the condition of women wage-earners warrants the assertion that some of the evils from which they suffer would not exist if women had the ballot..... In the states where women vote, there is far better enforcement of the laws whish protect working girls."
15. Because it is a maxim in war, "Always do the thing to which your adversary particularly objects." Every vicious interest in the country wolld rather continue to contend with woman's indirect influence than try to cope with woman's vote.
16. Because experience has proved it to be good. Women have for years been voting, literally by hundreds of thousands, in England, Scotland, Ireland, Australia, New Zealand, Canada, Wyoming, Colorado, Kansas, Utah and Idaho. In all these places put together, the opponents have not yet found a dozen respectable men who assert over their own names and addresses that the results have been bad; while scores of prominent men and women testify that it has done good.An ounce of fact is worth a ton of theory
