A data scientist's Senate race model is as unpredictable as the man it's trying to measure.

Our reading
A data scientist’s model tracks Senate race odds by calibrating betting site prices, but the real work is done by a professor who says Trump’s actions can move entire states. It’s a system that treats politics like a stock market, where the only thing more volatile than the numbers is the idea that anyone can predict the future.
The model’s live ticker shows probabilities shifting every 10 minutes, but the real drama is how much the numbers can change in a day. It’s like a casino where the house is also the dealer, and the only thing more uncertain than the outcome is whether the data is actually useful.
Despite the fluctuating odds, the model still says Democrats are in a strong position. But if Trump does something, the whole thing could shift again—because in this world, the only thing more powerful than a prediction is a tweet.
