DRIVING HOME THE ‘DISHONORABLE’ NARRATIVE…. Following up on an item from the weekend, the Obama campaign has apparently decided to challenge McCain directly on the issues of honesty and integrity, taking on McCain’s relentless dishonesty as a character issue.

The latest ad, released this morning, is called, “Honor.”

For those who can’t watch clips from your work computers, the spot starts by showing McCain, eight years ago, vowing to voters, “I will not take the low road to the highest office in this land.” From there, a voice-over starts quoting a series of items about the kind of campaign McCain is running: “What’s happened to John McCain? He’s running ‘the sleaziest ads ever.’ ‘Truly vile.’ ‘Dishonest smears’ that he repeats even after its been ‘exposed as a lie,’ ‘truth be damned.’ A ‘disgraceful, dishonorable campaign.’ After voting with Bush 90% of the time, proposing the same disastrous economic policies, it seems ‘deception’ is all he has left.”

For what it’s worth, I like the ad a lot, and not just because one of the quotes came from me (note the citation at the 15-second mark). There’s a genuine opportunity at hand for the Obama campaign to establish a legitimate narrative — McCain just can’t be trusted. It’s arguably the first attempt in a while for the Obama campaign to go on the offensive, and it has the added benefit of being accurate.

What’d you think of it?
