As in most other federal Alberta ridings outside of Calgary and Edmonton, it usually supports the major right-wing party of the day by landslide margins.

Lethbridge itself is somewhat friendlier to centre-left candidates, at least at the provincial level, which helps reduce the overall margins compared to surrounding ridings.

The Alberta New Democratic Party (NDP) won both seats in the provincial legislature from the city in the 2015 provincial election, but in 2019 lost the Lethbridge East riding to the United Conservative Party (UCP).

At the federal level, however, the NDP and the Liberals are no match for the overwhelming conservative bent of the more rural areas.
