Biden to make Obama's case to middle class

Associated Press

CHARLOTTE, N.C. (AP) — It's time for Joe Biden to show why President Barack Obama is keeping him as his running mate.

The vice president is set to address the thousands of delegates at the Democratic convention — and millions more watching at home — on Thursday evening. Advisers say Biden will tell what he saw from his front-row seat as Obama made some hard decisions. And he'll make the case that Republican rival Mitt Romney isn't suited to make the tough calls.

Biden's target audience is white, working-class voters. Look for him to use words such as "conviction" and "character." He also plans to talk about the decisions that have defined Obama's term in office, such as sending Navy SEALs to get Osama bin Laden and helping bail out Detroit's automakers.
