Absolutely. Probably the highest possible name recognition of any ticket, while Biden strongly appeals to moderates and Sanders energizes the most progressive members of the party. Both of them are likable and come off as at least mostly genuine, and both are solid debaters, particularly Biden. I don't see them having any trouble winning back the crucial WWC counties in WI/MI/PA that Clinton lost. Their age might be a tad discouraging, but I doubt it would be a serious issue.
Fmr. VP Joseph Biden (D-DE) / Sen. Bernie Sanders (D-VT) - 348 EVPresident Donald Trump (R-NY) / VP Michael Pence (R-IN) - 190Obama 2008 - IN. NC/OH/FL would all be very close but I see Biden/Sanders with the edge.
