"Certainly"? "Largest"? No, not certainly.
Obama's pick was a balance of what would be the best choice politically
and in terms of governing. Biden has many qualities that would make him a good vice president -- chief among them his readiness to assume the presidency if need be.
McCain's choice isn't about governing, it's just about winning elections.
One can say that he can't govern until he wins the election -- but Palin is still an afterthought there. He's basically saying a) he doesn't need a VP, b) he guarantees that he won't die (or be otherwise incapacitated). Those are both problematic assertions IMO.
