In South Korea, voters are heading to the polls today for a special election to fill the seat of former President Park Geun-hye, who was ousted and jailed on charges of bribery, extortion and abuse of power after massive street demonstrations in March. The front-running candidate, Moon Jae-in, has pledged to challenge the THAAD missile defense system the U.S. recently installed in South Korea. The most left-leaning candidate in the race, Sim Sang-jung, has campaigned on a platform of wealth redistribution, universal basic income, LGBT rights and other progressive causes.
