Democrat Kyrsten Sinema has defeated Republican Vernon Parker in Arizona's 9th District, The Associated Press is reporting.

The race for that seat has been one of the closest in the nation, and both parties were heavily invested in its outcome. Sinema has a nearly 6,000 vote lead over Parker, according to the AP, and, with her win, she becomes the first openly bisexual person elected to Congress.


Republicans believed Sinema to be too liberal for the newly created district, and attempted to portray her as such by highlighting controversial comments she had made about stay-at-home moms and drawing attention to her policy positions.

Democrats portrayed Parker as in lockstep with the Tea Party, and alleged that he would hurt children and families by cutting funding for the Department of Education.
