WASHINGTON – The election that delivered control of the U.S. House of Representatives to Republicans was awash in numbers — incumbents ousted, hundreds of millions in secret money, President Barack Obama’s 45 percent approval rating.

Yet the story of the victory could be told with one number: the 9.6 percent U.S. unemployment rate.

The anxiety Americans feel about their jobs led voters to turn the “Yes We Can” anthem of Obama’s 2008 presidential campaign into “No You Won’t” two years later.
