Obama good natured? Obama interrupted Roberts FIRST, which threw the whole thing off. He should be apologizes to Roberts.
I think Obama’s mistake was of a different magnitude from Roberts’. Roberts paused slightly after “I, Barack Hussein Obama...” causing Obama to start to repeat it. And, if he had watched Bush’s last Inauguration in preparation, there was a pause then and Bush said “I, George Walker Bush...” before “do solemnly swear” was administered.
Roberts’ mistake was bigger. He mangled the next phrase (put “faithfully” at the end; substituted “to” for “of” in front of “the United States”). That’s where the real problem started.
