Following a sudden GOP slide, a top data scientist’s model gives Democrats 90% odds of taking the Senate as Kansas trends blue in major shock

In a sudden shift, data scientist Thomas Miller's model predicts a near-certain Democratic takeover of the U.S. Senate, with a 90% chance of winning at least 51 seats. The model, Virtualtout.io, has seen GOP chances plunge from 23% to under 10% over the past few days. The key factor behind this rapid decline is that Democrats now lead in traditionally Republican strongholds, such as Kansas and Iowa.

Miller, a Northwestern University professor, correctly forecasted Democrats' victory in the Georgia Senate runoffs in early 2021 and predicted a Trump win in 2024. His methodology involves incorporating predictions market prices from Kalshi and Polymarket to translate into probabilities and crunching multiple time series factors driving the prediction markets.

Miller updates the probabilities every 10 minutes and notes that Trump's stumping has not positively impacted Republican chances. The model forecasts Democratic wins in states like Maine, Michigan, and Kansas, which were previously considered Republican strongholds. The trend towards the Democrats in recent days has surprised many, and the model will continue analyzing the swings in betting odds leading up to Election Day, aiming to be the first to call the races.
