Let me begin by saying I don't agree with everything you say all the time. Sometimes I am slightly suspect about your motives and the 'gist' behind some of your commentary, but this is spot on.
There was no reason for the person who TR you to do so. You spoke absolute truth to the issue. The sad legacy of this primary will be the progressive wing of the party turning on the only successful Democratic POTUS of their lifetime because they needed to denigrate his spouse and derail her chances. Bill's accomplishments were even downplayed by the nominee himself on the campaign trail by his continual raising up of other's accomplishments while refusing to acknowledge Bills. That was shameful, and anyone believeing otherwise has bought into the 'fairytale' about Bill and Hillary's rascism.
This issue alone is one of the reasons I simply do not trust those who hold themselves up as 'progressives' yet they continue to deride the Clinton years as shit.
Bill is a political force that still has drawing power and usefullness for the party. However, if I were Bill, the way he has been portrayed and treated this campaign season, I would happily sit home on my hands and read Mad magazine.
