The party in the electorate consists: exclusively of party identifiers. exclusively of party activists.

Explanation:

The party in the electorate is the biggest component, consisting of party identifiers (those who recognize themselves as existing segments of a political party) and party activists (party constituents who support to design and supervise party roles and preparation). Usually, somebody belongs to a political party because they correspond with several of its principal plans and maintain some of its candidates.

The party-in-the-electorate are those segments of the electoral public who examine themselves to be a member of a political party and/or who consistently favor the nominees of one party over the other.
