There have been 35 women in the United States Senate since the establishment of that body in 1789, meaning that out of the 1,897 Americans who have served in the United States Senate since that time, 1.85 percent of all Senators have been female. Women were first elected in numbers in 1992. Today 16 of the 100 US Senators are women.
http://en.wikipedia.org/wiki/Women_in_the_United_States_SenateTwenty-nine women have been or are currently serving as the governor of an American state, including two in an acting capacity. The first female governor was Nellie Tayloe Ross of Wyoming who was elected on November 4, 1924 and sworn in on January 5, 1925. She was preceded in office by her late husband William Ross. Also elected on November 4 was Miriam A. Ferguson of Texas, but she was not sworn in until January 21, 1925. The first female governor elected without being the wife or widow of a past state governor was Ella T. Grasso of Connecticut, elected in 1974 and sworn in on January 8, 1975.
Connecticut and Arizona are the only two states to have elected female governors from both major parties. New Hampshire has also had female governors from two parties, but Republican Vesta M. Roy served only in the acting capacity for a short time. Arizona was the first state where a female followed another female as governor (they were from different parties). Arizona also has had the most female governors with a total of three.
Currently, eight women are serving as governors of U.S. states. Between December 6, 2006, when Sarah Palin was inaugurated as the first female governor of Alaska, and January 14, 2008, when Kathleen Blanco left office as governor of Louisiana, a record nine women were serving as the chief executive of their states.
The District of Columbia and the U.S. Commonwealth of Puerto Rico, though not states, have also had female chief executives in the past.
