If Democrats want Hillary to be president, they need to find a primary challenger for her

Much of the conversation has focused on potential challenges from the Left. Is Clinton too close to the Wall Street-Goldman Sachs wing of the Democratic Party? Does she need to distance herself from the deregulatory policies of the Bill Clinton years? Is she too hawkish for the activists who helped make her vote for the Iraq War so costly back in the 2008 campaign?

It would be even more helpful to her election prospects if she were confronted in the primary with questions more likely to be raised by the Republican nominee in the fall: was the Russian “reset” policy naive? Was it wise for the US to leave Iraq without even a residual force in place? What specific aspect of US foreign policy was changed for the better under her watch? Does she agree that the Affordable Care Act was offered to the public under false pretenses?

If these issues raise uncomfortable questions for Democrats, Clinton has reasons not to be too unsettled. She no doubt remembers that another candidate for President had to explain his break with many root assumptions that Democrats held about issues ranging from crime to trade to welfare. And that debate during the 1992 primaries worked out pretty well for the nominee.
