From Weekly Standard Blog:
"So Obama's new ad, the first of the general election, "cites Public Law 110-181 when he talks about his efforts to extend 'health care for wounded troops who'd been neglected.'" The problem? Obama never showed up to the vote. He was actually too busy campaigning to make it back to Washington to vote for the bill, but wants the American people to think he deserves the credit. Sounds a lot like the 2005 Energy Bill, which Obama has the gall to attack John McCain on even though the junior senator from Illinois voted for it and McCain voted against it."

UPdate II:A poster at Daily Kos attempted to defend Obama, but towards the end of the post, notes that Obama offered two amendments that dealt with medical and mental health assessments and a temporary moratorium on discharges for personality disorders… but neither amendment was considered for a vote. Link.
UPDATE III: What a liar. The staff gets very frustrated when Obama lies and the media plays along. Link
UPDATE IV: If you don't have a record to run on, Just make one up! But as we all know, Obama doesn’t have much value at all when it comes to his experience or integrity. So the only way he has left to sell himself to the American public is to exaggerate his accomplishments. Link
