Difference between 大半 and 多数派


I understand that both 大半{たいはん} and 多数派{たすうは} can be translated as "majority".
Is there a difference between them in usage or nuance?




I think the major difference is that 大半{たいはん} means that it must be more than
half of the total group, but that 多数派{たすうは} only needs to be the subgroup with
the largest number of people.

That is to say in Japanese, 多数派 could be used to translate the English word
`plurality` wherein there is no absolute majority (no one has more than half
of the total group), but there is one group that has the largest fraction of
the votes.
