Rasmussen Reports says that John McCain has opened up a 20-point GOP primary lead over former Congressman J.D. Hayworth, according to its latest poll.
The latest Rasmussen Reports telephone survey of Likely GOP Primary Voters in the state shows McCain attracting 54% of the vote, while Hayworth earns 34%.
For Hayworth, this represents another decline in support. In April, he picked up 42% of the vote. That fell to 40% in May, 36% in June and 34% in July.
For McCain, the 54% level of support is his highest yet.
As always, take Rasmussen's polls with a big grain of salt, as their reliability has been questioned by other pollsters.
Regardless, it's looking more and more like Arizonans will get six more years of McCain.
