WASHINGTON – GOP Rep. Martha McSally and Democratic Rep. Kyrsten Sinema are running neck-and-neck in the Arizona Senate race, according to a poll released Monday.
The Arizona ABC 15/OH Predictive Insights poll found that 49 percent of the respondents said they support McSally, compared with 48 percent who said they support Sinema.
The sampling included 631 likely voters and was carried out Friday and Saturday. The poll has a margin of error of plus or minus 4 percentage points.
An Arizona ABC 15/OH Predictive Insights poll released on Thursday showed McSally leading Sinema by 7 percentage points. The poll came one day before Green Party candidate Angela Green dropped out of the race and endorsed Sinema. Recent polls showed Green with the support of 1-6 percent of likely voters.
Sinema, 42, is an attorney and has served in Congress since 2013. If elected, she would become the first openly bisexual member of the Senate.
McSally, 52, is a retired Air Force colonel. She has served in Congress since 2015.
The candidates are vying for the seat of retiring GOP Sen. Jeff Flake.
Arizona has never elected a woman to the Senate but that will change on Tuesday as both candidates on the ballot are female.
Polls say Republicans are likely to maintain control of the Senate and Democrats are likely to retake the House.
