He spent wayyy more than that. 7m on NY paid media alone.
My guess is that he has 5 million CoH, max

Sanders was down to $5.8 million in the bank by the end of April, showing the heavy toll that Wisconsin, New York and other April primaries took on the campaign's finances. Clinton, by contrast, closed the month with $30 million on hand.I guess that's why he and his minions had that temper tantrum. It's the end of the line for the Sanders campaign gravy train and grifters like Weaver and Devine will be forced to return to their day jobs.
