Barack Obama's campaign released its latest ad Tuesday. The spot, which will run in 18 potential battleground states, focuses on Obama's efforts to help secure the world's loose nuclear weapons.

The ad seems aimed at killing several birds. First, it's about boosting Obama's national security credentials and about showing one way in which he's experienced. And, in mentioning that he worked with Republican Sen. Richard Lugar on the issue, it portrays Obama as someone who can work across the aisle, a message that both Obama and presumptive Republican nominee John McCain are working to send this year.
