How do candidates compare in their swing state appeal?

in general i am very wary of "electability" arguments but it's interesting to see how various Dems compare with the Repubs in swing state this election cycle. This data comes to us from SUSA via Dailykos:

This month, responding to the complaints, SUSA decided to poll other Democrats in key states besides Clinton.

It was through the electability trap that we got John Kerry so let's not get too excited here but it is very encouraging (shocking!?) to note that the most progressive guy is also the most "electable". Swing Voters seem to find Edwards sharp contrasts with Republicans convincing. I hope that this is a statement about his populism rather than his race/gender. Unfortunately it is not easy to separate those factors out as all the republicans are white men and none of the other leading democratic women, such as Seblius, are running. All this to say that I am drawn to Edwards claim that he is the candidate of change and will stand up and fight special interests. I don't see Obama having the stomach or HRC having the desire to win that fight.
