Sarah Brisk Shoer took advantage of her new legal right to vote as soon as it was available. In 1919, she lived in Michigan, which on June 10, 1919 was the second state to ratify the 19th ammendment to the United States Constitution. The 19th Amendment was the National Suffrage Amendment, first introduced by Susan B. Anthony and Elizabeth Cady Stanton in 1878 and much later ratified on August 18, 1920 by the required number of states.
On October 16, 1920 Sarah registered to vote in Hancock, Houghton, Michigan. More importantly she voted in the November 1920 presidential contest between Warren G. Harding and James M. Cox, just three months after the 19th Ammendment was made law.
