Newest Liberal attack ad worst yet

A correspondent writes:

It's just released and it's horrible. I can't believe they would go so low. I'm shaking and almost crying in anger. Link to it here. You have to see it. What has the Liberal Party come to?

On a personal note, I can only add what a tremendous sense of sorrow I feel -- not anger, but truly, sorrow -- that a once-great party should stoop to such tactics. I used to respect Paul Martin, but this ... words fail me.
