Yes, he really said that Summers "did a heckuva job." The candidate that was gifted the opportunity to run against the legacy of one of the worst presidents in U.S. history has, as president, used Bush as his role model to continue many disastrous policies. It was strangely fitting that he would channel Bush's infamous praise ("Heckuva job Brownie") for the FEMA chief who failed New Orleans so badly in the hurricane.
Larry Summers is an epic failure like Michael "Heckuva job, Brownie" Brown. But at least Brown didn't pile up an extra trillion dollars in debt to no benefit.
