Electoral wipeout

An electoral wipeout occurs when a prominent or notably important main party wins no seat(s) in an election cycle; "wiped out" means no one secured victory, from that party, in the body that has conducted an election. It is the opposite for a loss at the rate of another party's "landslide victory"; the two descriptions are often used as journalistic reference to critique overall opinion or support for the defeated party given the districts which may be regarded as a usual traditional stronghold have also suffered abandonment in securing assumed victory.

A use of the phrase generally assumes that the returns were the product of a legitimate election; show elections to fraudulent legislatures regularly produce incredibly strong majorities for the ruling party (or parties).
