A lot has changed since 1922 when the first woman became one of 100 U.S. Senators.
Thirty-nine women have served in the U.S. Senate over the years and Tuesday’s election will introduce five more to the exclusive club.
It was a night of many firsts for women in the 2012 election – Elizabeth Warren became the first female senator from Massachusetts, Mazie Hirono became the first Asian-American woman elected to the Senate, and Tammy Baldwin became the U.S.’s first openly gay senator.
In addition, Republican Deb Fischer beat former two-term Democratic Senator Bob Kerrey to take over the seat from retiring Senator Ben Nelson, D-Neb. NBC News is now calling Democrat Heidi Heitkamp the apparent winner in her race against Rep. Rick Berg in North Dakota for that state’s open senate seat.
