Visions are long, life is short.
I think John Edwards understood this, and may be why he felt it important to pass his most passionate visions to Barack and Hillary. Whomever best embodies his visions will win my vote, if I don't for John.
I will "default to the vision".

To date, it seems that Barack is doing a better job of absorbing, and reflecting his visions, and so I am tending toward him. I wonder, though, if he would flinch when it came to learning all the truth about  the Bush Administration, and all their crimes and misanthropies. John would not flinch. Not so sure about Barack...or Hillary. She (and Bill) may well relish such action.

As I always said, with John you get better visions, but also better reality. If Barack and Hillary fail to understand the full reality of BushWorld, we all will be at a loss, because you cannot achieve your visions if you are not where you think you are. There has to be a ground of truth and reality...regardless of Bush and Cheney's ululating to the contrary.

We must ask the toughest of questions to all the candidates, and transcend the adolescent echo chamber proffered by the corpulent media.
