President Obama receives criticism from the left wing of the Democratic Party with respect to several national security and civil liberties issues. The first is is the closing of Guantanamo. Guantanamo remains open, largely due to Congressional insistance rather than any direct action on Obama's part. He asked Congress to close it and Congress said no, and that was the end of the fight. The second issue is the use of unmanned drones to kill suspected terrorists abroad, including terrorists who are American citizens.
Franklin Delano Roosevelt once said to a group of progressive reformers "I agree with you, I want to do it, now make me do it." The obvious implication there is that progressives have to convince enough of the public as to why the reform is needed so as to create a public clamor for the reform that is so loud and demanding that FDR would be forced to make the reform.
Would it surprise you to learn that keeping Guantanamo open and using drones is popular.... among liberals and Democrats?
