Bisexual Democrat Kyrsten Sinema flipped Arizona's competitive Senate seat

It’s been 30 years since Democrats held a Senate seat in Arizona. Democratic Rep. Kyrsten Sinema will be the first female Democrat to hold the position of Senator in Arizona.

She is also the first openly bisexual US Senator. On Monday, Republican Rep. Martha McSally conceded defeat.

On Monday night, Democratic Rep. Kyrsten Sinema had 1,097,321 votes or 49.68 percent. Her opposition, Republican Rep. Martha McSally had 1,059,124 votes or 47.96 percent.

In 2013, Sinema also became the first openly bisexual person to be seated in the House of Representatives. Winning against McSally will now make her the first openly bisexual US Senator.

Sinema and McSally were fighting over the seat held by retiring GOP Sen. Jeff Flake. Most of the midterm races produced clear winners and losers by Tuesday night, however, the Arizona contest was considered too close to call until Monday night.

The Democrat slowly developed a lead that grew as the days went by. On Monday evening, Sinema gave a victory speech where she honored the late Arizona Sen. John McCain.

She also referenced McCain's final address to Congress before his death and his call for civility in bipartisanship. During her speech she added:

"It won’t be easy, and it won’t happen overnight, but we can work together to meet the challenges our country faces.”

She further said:

"We can do this differently. For our country, for our future, for Senator McCain, and for each other I think we must."

Via Twitter, McSally conceded the race in a video statement. She said:

"I just called Kyrsten Sinema and congratulated her on being Arizona's first female senator after a hard fight battle. I wish her all success as she represents Arizona in the senate."

After her win, the new senator tweeted, "Thank you, Arizona. Let’s get to work.” Sinema represented a district based in the Phoenix suburb of Tempe as a congresswoman.

She is a former Green Party activist who became a centrist Democrat with one of the most conservative voting records among Democrats in Congress. Sinema was born on July 12, 1976.

She is an American politician who served as the US Representative for Arizona's 9th congressional district since 2013.
