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