The opening scene is a teaser from episode 17, I hate when a drama pull this kind of stuff. It's okay to tease a couple of episodes in advance but not a teaser from the ending. Speaking of the ending, the last two episodes were bad, they were leaning to heavily on old melodrama themes/cliches that doesn't work in the context of this drama. Most of the cast did a half-assed job, their performance came out as awkward and immature, especially from those who work in the campaign. The candidate's son Jang Sung Min was the worst character/actor in the dram, replace him with a stranger might be better.

Regarding the story and its events, there was no real big escalations that you might expect in a political focused drama, it was mostly the known generic jabs in a political context. They forced "In Yeong" and "Min Ki" plot line but then proceeded to brush it off aside without much regard. Their screen time appearance was very limited after that. The drama was passable at best.
