The problem with your idea of Trump bringing in people is that he hasn’t shown any ability to do so. He had majorities in 2017, then lost seats in 2018 and 2020, and wasn’t successful in getting his people elected in 2022. No reason to believe that would change in 2024.
Presidents routinely lose seats mid term. Anything post 2020 is suspect due to successful fraud through mail in voting. What candidate has made election fraud front and center?
