FILE - In this Nov. 3, 2008 file photo, then-Republican presidential candidate, Sen. John McCain, R-Ariz., points to the crowd during a rally in Henderson, Nev. FILE - In this Jan. 24, 2013 file photo, Sen. John Kerry, D-Mass., second from right, speaks with Senate Foreign Relations Committee member Sen. John McCain, R-Ariz., right, as he arrives for the start of his confirmation hearing to become the next top diplomat, replacing Secretary of State Hillary Rodham Clinton, center seated, on Capitol Hill in Washington. Sen. Elizabeth Warren, D-Mass. is at left. Republican McCain is a walking contradiction, assailing President Barack Obama over Libya and Syria one minute, cooperating with him the next on immigration and the budget. As friend or foe, the five-term Arizona senator _ his party’s presidential candidate in 2008 _ is giving Washington whiplash. He insists he's consistent. Whatever the issue, McCain is involved in nearly every hot topic. (AP Photo/Isaac Brekken)
