The night Barack Obama clinched the Democratic nomination for president, Green Day's Billie Joe Armstrong found himself experiencing an unfamiliar emotion: hope. "After his acceptance speech, I have to admit, it took me an hour to get the lump out of my throat," says Armstrong, whose band's American Idiot was the defining protest album of the Bush years. "Obama inspires people, and this country needs inspiration. People are jaded, pissed off and embarrassed."

Billie Joe Armstrong "I don't want it to turn into a cult of personality. He's not Magic Man. The great thing would be if he could lead by example and inspire people to get their own shit together."
