A “power rating” of members of Congress released last week by the nonpartisan company Knowlegis of Fairfax, Va., lists Arizona Sen. John McCain as the 11th most-powerful of the 100 U.S. senators. Arizona’s other Republican senator, Jon Kyl, is listed as the 13th most powerful.

In the 435-seat retiring House, Rep. Jim Kolbe, R-Ariz., is listed as the most powerful Arizonan, ranked 27th in the chamber….

…. Their findings, which can be viewed at www.congress.org, also indicate that GOP Rep. Rick Renzi comes out as the second-highest-ranked Arizonan in the House behind Kolbe, placing 101st overall.
