My opinion of your “poor” prediction is that cheating was as rampant in 2018 as it was in 2020. Remember how all (or maybe just the vast majority) of House races that looked like GOP wins suddenly, inexplicably turned around?
I think that wasn’t a coincidence. I think your predictions were pretty solid.
Going back, I do think that was part of it. But I think that a) “muh Russia,” b) Way too many Rs resigning leaving non-incumbents to fight for the seats, and c) too many RINOs like Comstock who sucked up money that should have been used in competitive races probably played a bigger role.
I’d say fraud probably cost us 5-8 seats, but the rest were on us and on the “muh Russia” non-scandal.
