Has he gone nuts? Clint Eastwood, Thursday night's previously unannounced “mystery speaker” at the Republican National Convention, had a primetime audience in stitches Thursday night as he quizzed an imaginary Barack Obama. Calling unemployment a “massive disgrace," Eastwood said it was “time for somebody else to come along and solve the problem.” He then lambasted Obama’s policies on Afghanistan, Gitmo, and more, addressing his complaints to an empty chair beside him. “I’m not going to shut up. It’s my turn,” he told the chair.
