Several datasets on parties and parliaments also have election data combined with numerous variables coding parties.
Finding voting results below the level of the electoral constituency/district (i.e., the level at which seats are distributed) can be very challenging. Each country reports at different levels of geographic aggregation. I have placed links to the lowest level I could find, which in all cases is below the constituency level. Emphasis is on parliamentary (specifically the lower house) elections.
