Bill Clinton's first-term Labor Secretary Bob Reich is one:
While it may be that all is fair in love, war, and politics, it’s not fair – indeed, it’s demeaning – for a former President to say things that are patently untrue (such as Obama’s anti-war position is a “fairy tale”) or to insinuate that Obama is injecting race into the race when the former President is himself doing it. Meanwhile, the attack ads being run in South Carolina by the Clinton camp which quote Obama as saying Republicans had all the ideas under Reagan, is disingenuous. For years, Bill Clinton and many other leading Democrats have made precisely the same point – that starting in the Reagan administration, Republicans put forth a range of new ideas while the Democrats sat on their hands. Many of these ideas were wrong-headed and dangerous, such as supply-side economics. But for too long Democrats failed counter with new ideas of their own; they wrongly assumed that the old Democratic positions and visions would be enough. Clinton’s 1992 campaign – indeed, the entire “New Democratic” message of the 1990s – was premised on the importance of taking back the initiative from the Republicans and offering Americans a new set of ideas and principles. Now, sadly, we’re witnessing a smear campaign against Obama that employs some of the worst aspects of the old politics.
Granted, Reich has been something of a Clinton critic ever since his 1997 book Locked In the Cabinet, but you do wonder how many other former Clintonites are starting to feel a bit queasy.
Update: This George Packer article quotes Reich and a number of other Clintonites getting off the bus.
