Kimberly Jensen's award-winning article, " 'Neither Head nor Tail to the Campaign': Esther Pohl Lovejoy and the Oregon Woman Suffrage Victory of 1912," gives the most complete analysis available on how Oregon women finally won the right to vote. Drawing from early twentieth-century newspaper accounts, extensive correspondence records, and archived material from a wide variety of local and national suffrage associations, Jensen's article fills the gap left by historians who have noted the importance of the 1912 suffrage vote but have not analyzed the cause of that victory.
The article was published in the Fall 2008 issue of the Oregon Historical Quarterly (the journal of record for Oregon history, published by the Oregon Historical Society) and is available here.
