(Phoenix, AZ) -- A last minute shift in Arizona's race for U.S. Senate. Green Party candidate Angela Green tells 12 News that she's dropping out of the race and throwing her support behind Democrat Kyrsten Sinema. Green has been pulling about 6 percent support in recent polls. And the race between McSally and Sinema has been separated by just a few percentage points. Greens tells 12 News that beside being outspent by millions, her exclusion from the one and only debate of the campaign took away any chance she had to get her message out to a wide audience.
