I'm not in Arizona, but there seems to have been a dirth of polls on this race. There was a November poll that showed it a dead heat, then a late January (?) poll (before Hayworth declared, and with McCain running frequent TV spots against JD) showing McCain ahead by 21 points. Both Rasmussen, and both outdated and probably meaningless.
I think if there were recent polls, someone would post them here as much interest as there is in the race. Maybe some Arizona people can add more information.
