Arizona's Green Party candidate announced she is dropping out of the state's Senate race and is endorsing the Democratic candidate Rep. Kyrsten Sinema.

Sinema is locked in a tight race with Republican Rep. Martha McSally to replace retiring Sen. Jeff Flake.

Angela Green told her supporters "to vote for a better Arizona, and that would be for Sinema."

Green said she was endorsing Sinema because her views more closely aligned with the Democratic candidate.

"There is a lot of other reasons that I can't support the other candidate," Green said.

McSally has a 7-point lead over Sinema, according to a new poll released Thursday.

A poll from NBC News shows Green receiving 6 percent of the vote and an average of polls from RealClearPolitics has Green getting 3 points.

Green's endorsement of Sinema could give her a late boost just days before the midterms.
