Oh? What's the process for that? Who chooses the delegates, and how?
It's up to the individual state, but the most likely method is for the delegates to be chosen amongst or appointed by the state legislatures. Consider this an end run around the miserable 17th amendment. Unlike a NY senator who can glide to D.C. on the votes of NYC and Albany alone, the state legislature is comprised of legislators from the rural districts which trend more Conservative.
The GOP currently enjoys a majority in the majority of state houses.
