Hollywood may be bashing Clint Eastwood's performance at the GOP convention, but Rush Limbaugh said Friday the reason is that he touched a nerve with leftist celebrities — and with the president himself. Pointing to the photo the Obama camp tweeted after midnight showing the back of the president's head above the office chair in the Oval Office, Mr. Limbaugh said that proves the White House was worried. And he wondered whether it was Mr. Obama himself. "It must have gotten to him because he tweeted at 12:30," Mr. Limbaugh said Friday on his radio program.
