Poll: McCain 54, Hayworth 28

Polls in this slugfest have been all over the place, making it hard to get a bead on where the race stands. And this poll is unlikely to change perceptions dramatically. But unlike some of the other polls, the statewide survey of 666 Arizona voters conducted between April 12 and April 25 includes Republicans and GOP-leaning independents who indicated they intend to participate in the Aug. 24 Republican primary.

Of those primary voters, McCain leads Hayworth 54 percent to 28 percent with another 18 percent undecided.
