LOS ANGELES (AP) — Clint Eastwood earned plenty of bad reviews for his latest performance: a bizarre, rambling endorsement of  Mitt Romney.
 

"Clint, my hero, is coming across as sad and  pathetic," tweeted film critic Roger Ebert as Eastwood ad-libbed  Thursday night to an audience of millions — and one empty chair — on  stage at the Republican National Convention in Tampa, Fla. "He didn't  need to do this to himself. It's unworthy of him."
 

Eastwood  carried on a kooky, long-winded conversation with an imaginary President  Barack Obama, telling him that he failed to deliver on his promises,  and it's time for Romney and his running mate, Paul Ryan, to take over.
