Amid this turmoil, a public opinion poll released on December 5 revealed that 7 out of 10 South Koreans support impeaching the president. The impeachment motion, proposed by the opposition party, is expected to be voted on between December 6 and 7.

According to a poll conducted by Realmeter for Energy Economy News on December 4, involving 504 adults nationwide, 73.6% of respondents supported the impeachment of President Yoon, with 65.8% strongly in favor and 7.7% somewhat in favor. Meanwhile, 24% opposed impeachment, and 2.4% withheld opinion.
