Arizona Senate poll: Ward 36, McSally 27, Arpaio 22

Ward came out ahead, with 36% of the vote, compared to 27% for McSally and 22% for Arpaio.

These latest numbers show a huge swing since a January poll, conducted the same day Arpaio announced his Senate run, which had the former Maricopa County sheriff in a dead heat with then-front runner McSally. In the January 9 results, Ward came in with the lowest percentage of the three candidates.

According to the Wednesday poll, 15% of likely GOP voters are still undecided in their primary choice.
