There would be a desperate scramble to replace her by the Democratic establishment, but between the time it takes to set up an entirely new campaign and the support the new candidate would have to build up overnight, Bernie would win the nomination.
In addition, hopefully HRC is shown to have clearly acted irresponsibly/negligently in her handling of sensitive materials on her private server (and as a result, she ends up in prison), but given her last name, I'm not holding my breath...
