I don't think any of the politics from the prequel trilogy lands. It's too cartoony for that.
Whereas Senator Mothma's story arc had me engrossed from beginning to end. From the complexities of a Senator's social life, to her financial difficulties, to the medieval like politics of marrying off her daughter for the sake of a political and financial alliance, to her risking more and more, to her brave and powerful speech condemning the empire.
There is nothing in the prequels that hits nearly as hard. Because it's all dialog the audience isn't paying attention to because the Jedi stuff is more engaging, and because the political stakes never seem that great.
