Leaks, National Security and Presidential Politics

The Obama White House is accused of leaking classified information to make the President look good and of punishing whistleblowers who make him look bad. Earlier this month, California Senator Dianne Feinstein expressed concern about threats to national security to CNN's Wolf Blitzer. Republican Senator John McCain wants a special prosecutor appointed to investigate White House leaks, but the President says that's not where the information is coming from. Others insist that the people have a right to know what the government's doing. Now the world knows the US is targeting specific people with drone strikes and that it attacked Iran's nuclear program with a computer virus. What new dangers have been created? Is it all about the President's re-election campaign? Is there anything new about leaking?
