The Fight Between Bernie Sanders And Hillary Clinton Is Officially Super Ugly

WASHINGTON -- A former executive director of the congressional Joint Economic Committee on Thursday accused columnist Paul Krugman and four prominent Democratic economists of dishonestly smearing an academic in order to score political points for Hillary Clinton.

The dispute, which is ostensibly over the ultimate cost of Bernie Sanders' economic agenda, is more than a simple war among wonks. It demonstrates that elite economists -- not merely paid campaign operatives -- are fueling the ugly escalation of hostilities between major factions of the Democratic Party as the presidential primary continues.
