Los Angeles (CNN) - After a tumultuous week marked by Republican hand-wringing over his comments on unrest in Libya and Egypt, Mitt Romney is going back to the beginning. The GOP nominee is refocusing his message on the issue repeatedly singled-out by campaign advisers as the one that will decide the election: the economy.

Based on excerpts released from a speech Romney is scheduled to deliver to the U.S. Hispanic Chamber of Commerce on Monday in Los Angeles and two new TV ads, Romney appears to be starting the week with a simpler, easier to understand economic pitch to voters.
