Elections are propaganda events that are used by the ruling class to justify whatever changes they want to make. There were two sides, they engaged in conflict, and one side won; this is the reason for the change. The election is more important that the subsequent administration.

Compare with a one-party state like China. How does the CPC justify changes in policy? Changes in conditions. The ruling class in the West cannot be this honest, since the only changing conditions they care about are their profits, so they stage conflicts instead.
