If the raikage has knowledge, he will ignore sasori and kakuzu from the start and go strait for deidara, before deidara can make his dragon. If he does this he will win, since neither kakuzu or sasori have the sheer offensive capacity to damage him.
If deidara gets to make his dragon and they all fly into the sky, then they will eventually win.
I see the raikage winning more than losing.
