Don’t take all I’m saying as gospel as I’m not that up on the system but my understanding.
Remember the gop and democrat are two different events.
There are some 1861 precincts covering the 99 counties. The locals gather at their precinct
at 7pm local time and begin the process. They can voice support for their candidate or not
and finally a vote is taken. I’m not sure if this is winner take all or proportional. After
the precinct level the process moves to the county level and begins anew. After that one they
move the congressional district level for the next process. Then comes the final selection at
the state level shortly before the GOP Convention in mid year.
You are correct.
Unfortunately, it is winner takes all. We watched this one year when our precinct caucus was over-run by Paul-bots. (Even more sickening was that you could tell that all of these people were straight out libs.)
It’s all about turnout. Just 5 - 10 people can make a big difference.
