With Oh Se-hoon acquitted, Cho Kuk is confirmed to finish 3rd in Pyeongtaek

If Oh Se-hoon had been found guilty, he would have been forced to run for the next Seoul Mayor or would have had to nominate someone else to run.
Then, there would have been an uproar over accountability, potentially shifting the general election to a Kim Min-seok system or moving toward an emergency response committee.
As long as Kim Min-seok holds his position firmly, there will be no party merger, and the possibility for Cho Kuk becomes even slimmer.
I'd bet everything I own that Cho Kuk won't be running via the proportional representation system again.
