Democratic Sen. Barack Obama and his wife, Michelle, made $4.2 million last year as widespread interest in the presidential candidate pushed the sales of his two books. In tax returns the campaign released Wednesday, the Obamas reported a significant jump in their income from the previous year as profits from the books Dreams From My Father and The Audacity of Hope accounted for some $4 million. The Obamas paid federal taxes of $1.4 million and donated $240,370 to charity.
