Arizona Representative Kyrsten Sinema has won her party's nomination to replace Jeff Flake in the U.S. Senate.
Sinema will defeat primary opponent Deedra Abboud, according to an Associated Press race projection.
Sinema, who has served in the U.S. House of Representatives since 2012, will go on to face fellow Representative Martha McSally, Dr. Kelli Ward or former Maricopa County Sheriff Joe Arpaio--the three leading candidates on the Republican side.
In her Senate campaign, Sinema focused on affordable health care and her willingness to work across the aisle. She had a significant cash advantage and deep well of establishment support.
The seat being vacated by Flake's retirement is considered a key potential pickup for Democrats in their bid to take control of the Senate in November.
