As opposed to the solid conservatives in Pyongyang?
In South Korea, “lefties” are those who call for appeasement and a utopian/hippie-dippie Marxist unification with the North. They are typically anti-American and blame the USA for the 70 year standoff. Ironically, the timing of Moon Jae In’s presidency plus Kim Jong Un’s relative youth leave an opening for Trump to negotiate (but on our terms of course.)
Current elephant in the room in S. Korea is its prior conservative and first female president: Park Geun-Hye. She was impeached over a year ago and sentenced to 30 years in jail over trumped up charges even more insane than our bogus Mueller/FBI investigation we got going on over here.
She is the daughter of President Park Chung Hee (served from 1963 - 1979) who was known to rule with an iron hand, yet is credited for building the country up into the economic power it is today. He and his wife were both assassinated.
However had Park Geun-Hye and the conservatives remained in power, Trump may not have achieved what he had this week...as they tend to take a harder-line hawkish stance with the North.
