Question

The rank-and-file members who carry out the party's electioneering efforts are the ______.

Answer 1

The rank-and-file members who carry out the party's electioneering efforts are the "party activists".

In political parties a rank and file member is the one who although support a party but do not get a high position formally inside that political union. The phrase rank-and-file originates from the military, where a rank means fighters standing next to each other in succession, and file alludes to troopers stalled behind each other.
