Bill Clinton to argue Obama re-election is critical for economy

Former US President Bill Clinton will argue in his speech to the Democratic convention on Wednesday that President Barack Obama's re-election is critical to restoring a vibrant, job-generating economy.

Clinton, the party's most popular elder statesman, will highlight the second night of the convention with a speech designed to remind voters of the budget surpluses and job growth he led in the 1990s during his two terms in the White House. (Reuters)
