Doubt it
If the Democrats look at recent history, they'll find that left-ish parties do best when steered back to the middle.
Worked for Clinton, worked for Schroeder, worked for Blair (he's gone so far that the traditional Centre party - the Liberal Democrats - are now to the left of him).
Perhaps more importantly they need to be more focused. The lack of a unifying message was likely the biggest undoing, and that lies at the feet of McAulliffe.
He's outta here.
Cheers,
Tony
