On May 21, 1919, the House of Representatives voted on House Joint Resolution 1 (H.J. Res. 1), which proposed a constitutional amendment granting women suffrage. This tally sheet shows the results of that vote. A clerk read aloud the names of Members twice, allowing them two opportunities to vote yea or nay. Blue ink indicated those who voted during the first reading of names, while red indicated respondents to the second reading. The tally sheet also indicated the political party of each Member. Names of Members belonging to the then majority party (the Republicans) appeared in Roman font, while Members of the minority party (the Democrats) appeared in italics.
On first glance, the tally sheet shows the final vote as 303–88. However, the clerk who recorded the votes on this tally sheet made two errors during the second round of voting. By incorrectly numbering the votes in the first column, the total vote was off by one nay vote and one yea vote. When added correctly, the yeas outnumbered the nays 304–89. The resolution passed the House and went to the Senate, which approved it on June 4. It then took more than a year for the amendment to achieve ratification in three-fourths of the states, as required by the Constitution. The U.S. Secretary of State certified it as the 19th Amendment to the Constitution on August 26, 1920, allowing many women nationwide to head to the polls that November.
