[1][2] As early as 1850, her attention was called to the subject of women's suffrage by reading the proceedings of the first Woman's Rights Convention held in Worcester, Massachusetts.
[1] She was associated with Lucy Stone, Julia Ward Howe, Susan B. Anthony, and other national leaders in the reform, often speaking with them at conventions in various states.
[1] She organized women's suffrage societies in Berkshire, Essex, Hampden, Plymouth, and Worcester Counties.
[2] In November 1879, Campbell settled in Iowa and continued active in the suffrage cause, taking part in all of the state campaigns.
[1] She worked with American Woman Suffrage Association to attempt toamend the Michigan Constitution to allow women to vote, in 1874 but it was defeated, 136,000-40,000.
[6] Campbell moved to the territory, spending much of 1875 and 1876 trying to convince the Colorado constitutional convention to give women the right to vote.
[7] Campbell returned to work on that campaign, giving lectures to drunken miners in small schoolhouses and on the banks of rivers.
[7] To get to some locations, she traveled up the sides of mountains on a "sure-footed little burro" along dangerous trails where they could have plunged thousands of feet to their deaths.
