We told you about how the Clinton campaign preemptively attacked the Sanders campaign for a reportedly negative ad that had been produced but had not yet aired. It was reacting to a New York Times report which said "The campaign’s ad makers have prepared two sets of commercials: One continues the feel-good tone of 'America,' ... The other takes aim at a central vulnerability of Mrs. Clinton, her Wall Street ties..." "We have options to go in different directions," said a campaign official.

Now the Sanders campaign has taken the latter route, releasing an ad called "The Problem." But while it may "take aim" at Clinton, it does not mention her by name. The boogeyman in the ad is Wall Street investment bank Goldman Sachs.

Is Sanders Attacking Clinton or Goldman Sachs?

In the opening frame, we see the Goldman Sachs name in 3D as part of a sweeping aerial view of its corporate headquarters. The narrator sets the scene: "They're one of the Wall Street banks that triggered the financial meltdown. Goldman Sachs. Just settled with authorities for their part in the crisis that put seven million out of work and millions out of their homes."

The camera seemingly zooms through a window inside the Goldman Sachs boardroom. "How does Wall Street get away with it?" the narrator asks. The answer is on a screen inside the boardroom. "Millions in campaign contributions and speaking fees."

The narrator concludes, "Our economy works for Wall Street, because it's rigged by Wall Street. And that's the problem. As long as Washington is bought and paid for, we can’t build an economy that works for people."

The allusion to Clinton is never stated, but on the stump, Sanders has been more direct in tagging Clinton as a recipient of Wall Street campaign cash.

The Clinton Campaign Plays The Umbrage Card

That's enough for the Clinton campaign to assert Sanders is violating his pledge to eschew negative ads. In a written statement, the Clinton campaign said "This last-minute sneak attack from the Sanders campaign is clearly meant to plaster the Iowa airwaves in the days before the caucus with negative ads slamming Hillary Clinton, without giving our campaign time to respond."

That seems awfully histrionic. The Clintons have been aggressive campaigners for a long time. They have doled out worse, and been the recipients of far worse, than an ad which fails to even mention the opponent's name.

But Bernie is running as someone who is supposed to above brass knuckles politics. Will voters see his attempt to get close to, but not cross, the line as an example of the same old same old? The Clinton campaign is at least going to prosecute that case in the final days before Iowa.
