If the one of the Democratic campaign wants to do a real attack ad, against a primary opponent, in a perfect world, it should fulfill the following requirements:

• It should be the truth.
• It should address a real concern of Democratic voters.
• It should <span style="font-weight: bold;">not</span> be something that the Republicans can use against the target if they win the general.

On to the Ad:

(Cue sinister music, go with spot of gray on the screen, which will slowly pull back as the ad progresses and reveal itself to be a scary black and white picture of John McCain)
In 2002, John McCain said that the ads accusing Max Cleland, who lost one arm and both legs serving in the military, were "Worse than disgraceful".

Now John McCain has hired Bo Harmon, the man behind that ad campaign as his national political director.

We know that the Republicans will be throwing every lie and slander they can find against the Democratic Nominee, and we know that Barack Obama has never been in a seriously contested election against a Republican.

Over the past 16 years, the Republican swift boaters came after Hillary Clinton with accusations of everything except eating puppies, and she's still standing.

The stakes are too high this November to take an audacious chance with your primary vote.

You will notice that this is a devastating ad, but it gives the Republicans nothing to use in the general.
