It could be some anonymous Senator. There were only seven election objectors in 2021-maybe someone like Hyde-Smith or Roger Marshall is secretly pretty awful.
I don't think that conspirancies should be considered conservatives.
I think that very conservative in this context should mean very fiscal conservative (including free trade) and very social conservative.
