resident Obama accepted the Democratic nomination for a second term on Thursday, in a speech arguing that his policies are working to bring the country back from economic calamity while his opponent, Republican Mitt Romney, offers proposals that would take us backward. Republicans "want your vote,  but they don't want you to know their plan," Obama said. "And that's because all they have to offer is the same prescription they've had for the last 30 years." Obama was preceded by Vice President Joe Biden, who testified that Obama has a "spine of steel" and reminded voters that "Osama bin Laden is dead. General Motors is alive."
