The 17th amendment has nothing to do with term limits, and states that are safely controlled by one party (e.g. the Massachuttes state legislature or the Idaho state legislature) would have no problem appointing a party insider to serve as U.S. Senator for life, so I’ll have to disagree with you there.
If the 17th amendment were repealed, a Ted Cruz type would stand zero chance of being selected by the establishment politicians in the state legislature.
That's a nice straw man you've got right there. Who said it did?
Love your straw men. Just because our broken system managed to miraculously produce a terrific politician like Cruz doesn't mean it's not worthy of serious criticism. We managed, despite the system, to get a Cruz, but we're also stuck with the likes of worthless troglodytes like Roberts, Cochran, McCain, Graham, etc., who do nothing for their home states, but yet manage to enrich themselves and their pals in power.
You're all over the map with your attempts at logical thinking and argumentation there, kemosabe.
