Here is a preview into tomorrow's analysis of predictions, based on Sabato's new changes.

Sabato's changes added two more House seats for Republicans. Looking good!

Using the expert ratings above, the results of 32,000 simulated elections are listed in the table below. The definitions of the columns are:

"GOP House Seats P10” – the value where the probability of the actual number being lower is 10%.
”GOP House Seats EV” – the expected value (mean) or probability-weighted average of the simulation.
”GOP House Seats P90” – the value where the probability of the actual number being lower is 90%. Or, it is the value where the probability of the actual number being higher is 10%.
”Probability of 218” – The probability associated with value 218 (the House majority goal).
”GOP Gain” – The difference between the GOP EV and the current number of seats (179), rounded down.
