FILE - In this March 4, 2009 file photo, Sen. John McCain, R-Ariz., looks on as President Barack Obama makes remarks on government contracts reform in the Eisenhower Executive Office Building on the White House campus in Washington. In a case of strange bedfellows in American politics, Obama and his re-election advisers are waxing nostalgic for the man the president defeated last time around. They're embracing McCain as a reasonable voice on climate change and immigration, someone who took on extremism in his own party. (AP Photo/Gerald Herbert, File)
