Failed big vote. Worth restarting?

Heyo, I'm on my first time playthrough and was trying to play blind, without looking anything up. I was going for a democratic reformer route but I failed the big on the constitutional amendments...by one...

I am quite bummed out about it because I thought I was doing well. Unfortunately I am not even sure what I did wrong or what I could have done differently.

I wanted to ask if the votes is final or if its worth reloading some chapters and fix it with the help of the wiki.

Thanks for your help c:
