You are not being fair to ER
I, like ER, am a long time movie fan of Clint. It was indeed a sad thing to watch. But Clint was making a political pitch and that makes his speech fair game. Like anyone else who drops the ball during such a pitch he deserves to get roasted. And he has been by all sides. Even Scott Walker admitted he was cringing, and said it would have been wiser to show the Romney biography video that was nixed just to make room for Clint. It was a disaster. Whoever made the call to let him go onstage unscripted was a moron.
And now, the day after, more people are talking about Clint's meltdown than Romney's big speech.
