FILE - In this July 27, 2011, file photo Rep. Jeff Flake, R-Ariz., from left, Rep. John Sullivan, R-Okla., and Rep. Bill Shuster, R-Pa., confer in a hallway as Speaker of the House John Boehner tries to retool legislation to raise the nation's debt limit at the Capitol in Washington. Since his first House campaign a dozen years ago, Flake has worked diligently to cast himself as a conservative gadfly, willing to buck GOP leaders and even a Republican president. But a GOP primary opponent and Democrats are portraying him as a Washington insider, who should not get to succeed retiring Sen. Jon Kyl, R-Ariz., because he worked as a lobbyist 20 years ago for a Namibian uranium operation with ties to Iran. (AP Photo/J. Scott Applewhite, File)
