“But why would Ben Sasse decide to be a communist and then pretend to be a conservative?”
Lol!
As voters, we interpret the actions of politicians. This is how the system works.
Ben Sasse opposes MAGA.
When a Senator claims to be a conservative republican but then opposes the one political movement advancing American values, we can accurately interpret his ideology to be anti-American.
The major anti-American, activist ideology is communism.
One of the primary strategies of the communist movement is to infiltrate conservatism by disguising communists as fellow conservatives.
Many of the RINOs are such infiltrators.
