Indiana ? John Edwards didn’t have to dodge tough questions from an Indiana University audience Tuesday, when the former presidential candidate returned to the stage three months after admitting to an extramarital affair.

The Democrat’s 30-minute speech covered politics, poverty and his hopes for America and the world and he later discussed President-elect Obama and other topics from the audience.

But the half-hour question-and-answer period featured only written queries that had been submitted before his speech – and the affair he has acknowledged with filmmaker Rielle Hunter didn’t surface.

After his public statements in August, Edwards said he did not plan to speak about the affair again.
