Eh, maybe. But I personally would find a Thedosian version of FiveThirtyEight to be more weird than helpful!
If you're worried about the election, listen in with some of the Val Royeaux gossips. They almost always have the right answer. And if you know where it's leaning early on, you can make later dialogue choices that can hopefully tip the balance in the direction you want it to go.
It's not really that I want a thorough in-depth analysis, but you know... I've built myself up to be one of the most powerful individuals in Thedas, at the head of an organisation that has an extensive spy network, a powerful army and the nobility of Orlais, Ferelden and the Free Marches cowering before it, and yet when one of three women from my inner circle is chosen to be Divine, I have no clue what the thought process behind the decision was other than to listen to gossips on the streets of Val Royeaux? That feels very weird. It jarred me out of what I'd found to be a satisfying ending up until that point.
I think though, that in some ways this is simply the game being a victim of its own success. In a similar way to failure in the final Lavellan war table mission not having any effect on your inquisitor. You feel it when it fails, because at other times it feels so real. I think that being realistic, it would've probably needed a few years of extra development time/budget to address all the nit-picks that one can make, and given EA's record they were lucky to get as much time as they did.
