The number of women in the Senate could increase by four or more above the current 20, with as many as three female minorities. It would be the highest number of women in the Senate in history, but nowhere near the percentage of females in the general population.
A record 167 women are running for the House. While outcomes are uncertain, analysts predict the number of women in the House for the 115th Congress that convenes Jan. 3 will exceed the current 84.
The new Congress could have some familiar names, with several former members seeking their old seats.
Twenty women now serve in the Senate, a total likely to rise next year.
