AZ-Sen GOP Poll Watch: Sheriff Joe Arpaio Leads the Republican Pack

Maricopa, Ariz. Sheriff Joe Arpaio prepares to speak to a crowd in the East Room on the grounds of the Nixon Presidential Library & Museum in Yorba Linda, Calif. on Tuesday, Feb. 8, 2011

If Sheriff Joe runs will he be a formidable candidate?

Maricopa County Sheriff Joe Arpaio led a field of potential Republican Senate candidates in Arizona with 21 percent in a poll of likely GOP primary voters last week.

Rep. Jeff Flake, who announced his candidacy for the seat of retiring Senate Minority Whip Jon Kyl (R-Ariz.) on Monday, finished second with 16.8 percent in the Summit Consulting Group survey. Former Rep. J.D. Hayworth took third, with 16.6 percent. He was unsuccessful in his primary challenge to Sen. John McCain last year.

The auto-dial poll of 1,881 likely GOP primary voters was conducted Thursday. It had a margin of error of 3 percentage points, which would put the top three finishers in a statistical tie.

Perhaps, but I think the nominee will likely be GOP Rep. Jeff Flake. I doubt Sheriff Joe runs – Maricopa County Sheriff is a better position anyway.

But, I would relish the fireworks between Sheriff Joe and former Arizona Governor Janet Napolitano race though.
