This is a fairly brutal appraisal of McCain's pathological campaign. 

As the campaign moves towards a focus on the economy, it's worth keeping in mind that McCain's lies are relevant because they demonstrate the fundamental emptiness of his campaign. He is devoid of ideas and solutions; lies are the only thing McCain has left.

We saw that today when Barack Obama gave a thorough speech on his economic vision -- and John McCain proposed a 9/11 commission.

So while McCain is busy chasing the economy to the gates of hell, Obama is talking about ways to put things rightside up again.

McCain won't get us out of the ditch we're in -- Obama will. And that's what this election will come down to, in the end.
