I was reading a Wikipedia page when I ran into this passage:
Wu and Teachout ran against Andrew Cuomo, the incumbent governor, and Kathy Hochul, an upstate Democrat and former Representative in the House. Teachout and Wu ran to the left of Cuomo and Hochul. Hochul won the race for Lieutenant Governor; Wu took 40% of the popular vote.
Intuitively I understood left to mean Left politics as in the left wing. From the context, however, it seems the sentence in question is saying Teachout and Wu lost to Cuomo and Hochul. So does run to the left of mean be beat by? Does left carry the sense of not as good as?
If left here indeed refers to the political left, is "run to someone's left" idiomatic?
