(CBS) -- In Arizona, the race to replace outgoing Senator Jeff Flake is coming down to the wire, with two women vying to fill the seat.
"We have to crack down on sanctuary cities, ms13 gangs, build the wall and secure the border. There is so much at stake," said GOP candidate Martha McSally.
"Women don't really care about political parties or ideology. They don't care who gets the credit. They just roll up their sleeves and get the work done," said Democratic candidate Representative Kyrsten Sinema.
The close contest is one of a record 33 races nationwide where both the Republican and Democrat nominees are women. Debbie Walsh at the Center for American Women and Politics is keeping count.
"We're not just, kind of, inching up over a record. We're kind of blowing through the record," she said.
Nationwide: 23 women are running to serve in the Senate, 237 women are running for House seats, and 16 women are running for governor.
"There may have been sort of a trigger moment of the election of Donald Trump, but these women are running because of healthcare issues, climate change, gun violence, education issues."
Congress could welcome its first-ever Somali-American member with Minnesota's Ilhan Omar, and first Native-American woman with Sharice Davids from Kansas. Stacey Abrams in Georgia is the first black woman ever nominated by a major party for governor.
"We hope this is the beginning of a new normal for women as candidates, where they are stepping up and they are saying, I'm going to run, I'm going to make sure I have a voice," she said.
A woman will have a voice as Arizona's senator... The only suspense is which one.
