WASHINGTON (AP) — President Barack Obama’s re-election team, seeking to infuse a bit of positivity into the biting general election campaign, released a new television advertisement Monday portraying an America on the rise and urging voters to stick with the president.

In a shift from many of the campaign’s earlier ads, this latest commercial focuses entirely on promoting Obama’s record and makes no direct attacks on his presumptive Republican presidential rival, Mitt Romney.

The approach underscores the campaign’s recognition that the president can’t win a second term simply by attacking his opponent. Obama also needs to make the case that, despite continued economic unease, he has made things better for the American people and is the right steward for the economy going forward.

The commercial credits Obama with pulling the nation’s economy back from the brink of recession and saving the U.S. automobile industry. It also highlights what the campaign sees as the president’s foreign policy accomplishments, including killing Osama bin Laden and ending the war in Iraq.

In the ad, a narrator says of the U.S. economy, “We’re not there yet, it’s still too hard for too many. But we’re coming back.”

The Romney campaign responded swiftly, with spokeswoman Amanda Hennenberg said “Americans know they’re not better off than they were four years ago.” She ticked through areas of the economy where the Romney campaign says Obama has failed, including high gas prices and home foreclosures.
