The Clinton strategy of marginalizing Obama as “the black candidate” and claiming that Obama was a Reagan supporter strikes at the very heart of the mulicultural vision, at the very heart of the Left-liberal identity. It cannot be compartmentalized as a defense of progressive ideals or the progressive movement because there is no significant ideological difference between Sens. Clinton and Obama. Moreover, the Democrats’ success in 2006, combined with their belief that this will be a “change” election cycle, makes the environment much different from the 1990s, when the Clintons were seen as first arresting the advance of the Right, later as the only bulwark against a GOP-led Congress. Thus, the relentless, overweening ambition and narcissism of the Clintons and their resort to racial politics is so nakedly exposed that Left-liberals are unable to avert their eyes from it.

Of course, it remains possible — perhaps even probable — that Left-liberals would rally to the Clintons again, should she win the nomination and even the general election. But I would still suggest that at the margins, this campaign, in this political environment, has forced Left-liberals to see the Clintons in a way that erodes the intensity of support they enjoyed in the 1990s. The scales have fallen.
