On April 17, Arizona held a primary election for the Democratic, Republican, and Green Parties, so that each of these parties could choose a nominee for U.S. House, 8th district. The special election will be June 12.

The Green Party primary ballot contained one name, Charlie Manolakis. Preliminary results show he polled 113 votes. He had one declared write-in opponent, Richard Grayson, who polled 19 votes. However, preliminary election returns are not always accurate for write-in returns.
