Elizabeth Warren takes the stage for her acceptance speech on Nov. 6 in Boston, Mass. after beating incumbent U.S. Senator Scott Brown in a highly contested and closely watched race that went down to the wire.
Nearly all of the female senator incumbents across the country were re-elected along with Warren, and voters also welcomed a handful of newcomers to to the nation's upper legislative chamber: Mazie Hirono of Hawaii, Tammy Baldwin of Wisconsin, Heidi Heitkamp of North Dakota and Deb Fischer of Nebraska. These new female additions to the Senate come in the wake of the impending retirements of Republican senators Olympia Snowe of Maine and Kay Bailey Hutchison of Texas.
Although 19 percent may not sound impressive given that women make up more than half of the U.S. population, it's still an important landmark in U.S. history.

U.S. Sen. Claire McCaskill greets supporters during an election night party on Nov. 6 in St. Louis, Mo. Democratic incumbent McCaskill was challenged by Republican Todd Akin, who lost his early post-primary lead after making his now famous "legitimate rape" comments.
