Methodology - 2022 U.S. House Election Model
The 2022 election models were a big shift away from the very primitive techniques I used with the 2020 models. The only exception to this was with the U.S. House model, as I did not have time to recreate that with the updated strategy. Because of this, all house race predictions were based on who won more categories like in previous years.

With the Fundraising category, the percentage for each party is based on their total campaign receipts in relation to the total receipts for that seat raised by all parties. If John Doe (R) has $500 and John Doe II (D) has $500, then both parties get a 50% rating for this category. This data comes straight from the FEC. For the Recent History category, I used historical data from 270ToWin to find the percentage of the past 12 or so elections that each party had won. The Last Election category was simply the percent of the vote in the last election for this particular seat, which I got from Wikipedia. The Expert Forecast category looks at 270ToWin's Consensus Forecast Map and assigns each color a percent value, ranging from 50% to 70% depending on how safe a race is. The Polls category is pretty straightforward, with it of course just being dependent on how a party's candidate is polling in that race. This data comes from FiveThirtyEight's polling averages, or if no average is available whatever the latest poll was. The 2022 House model did not account for undecided voters/remaining votes with polls, so if you had a poll result of 49% and 49%, it would not split the remaining 2% up between the two candidates like with future models.
Race Ratings
The race ratings took into account the winner of each category and picked a party depending on who won more categories. Unfortuantely, this was a slightly opinion-based process as I didn't have a specific formula I was sticking with. If a party won all five categories, then they would be the predicted winner, as is the same with four or three categories.
