Who would you suggest implement such a change?
As I'm sure you know, the selection of candidates of various parties isn't addressed by the Constitution. The Republican Party could chose its nominee with tarot cards, as far as the Constitution is concerned.
So your complaint is, I assume, directed at the national political parties. Even there, there are difficulties, likely intractable ones. Primary dates, or caucus dates, or state convention dates, and their methodology, or the decision to have none of the above, are generally determined by each state legislature. Certainly, the national parties can and do exert pressure on the various state legislatures to set dates consistent with their strategic goals, even going so far as to refuse to accept the primary results of a state, but the fact is that the legislators of the 50 states will do as they please.
I would resectfully suggest you crusade for a more readily achievable goal -- Mideast peace, say, or that long-awaited Los Angeles to Honolulu bridge.
I was thinking of a more achievable goal, like getting San Francisco to be a conservative city. :)
I realize it would have to be a coordinated effort among the states because the Feds don’t control the primary process. I don’t know how that would happen, but it would be nice if it could.
Texas is an open primary state. You’ve never seen so many people cross over to the dark side and vote for Hillary Clinton in Operation Chaos at our precint. It was very obvious what people were doing and was hilarious. I just couldn’t bring myself to do it.
