Garry Ghapel Hill at Riverdaughter chronicles the continuous B0 efforts to trash Bill Clinton’s legacy.

Not only I believe it was part of the price of the 100 million & media deal with the RNC (besides getting rid of Hillary, of course), but it was the official strategy of the campaign:

Advisers believe that the more the Clintons poke at Obama, the more sympathetic he becomes, and the more she plays into his contention that she’s a divisive, polarizing figure; Obama’s polling shows and his campaign’s strategists sense that it reminds Democrats in the interior of the country of the Clinton of yore: cold, unlikable, sarcastic — and coastal. In states like Arizona, Kansas and Idaho and Missouri, Clinton will scare off independents and will lose support among younger women, in particular.

In other words, the whole “red states” caucases was fueled by Clinton hatred to Democrats for a Day (or rented Republicans)

Also, a little better known is the race memo, issued before South Carolina – the Sharptonizing of the Clintons

The document provides an indication that, in private, the Obama campaign is seeking to capitalize on the view – and push the narrative – that the Clintons are using race-related issues for political leverage. In public, the Obama campaign has denied that they are trying to propagate such a perception, noting that the document never was sent to the press.
