Record wins for women in Senate

Women will occupy a record number of

U.S. Senate seats -- roughly one in five -- in January,

following historic victories in Tuesday's elections. As many as six women could win election to the Senate once

all ballots are counted, and currently, 17 women--

the most yet-- serve in the chamber.
