undervote 

Voting for fewer candidates than the number of open positions. Electronic voting machines usually highlight undervotes to remind the voter that they can choose to vote for more people.

There were ten people running for five City Council at-large seats, but I only cared about electing two. Because this was an undervote, the voting machine kept flashing a red light in that section of the ballot, but I didn't choose any more names.
