I don’t know, that’s why I’m asking. I know that on his way out the door he changed the way California nominates its Republican candidates, as a response to Proposition 14. No more competing for the nomination, the GOP picks, and that’s who runs. I would not like to see that on a national level.
My husband was our Republican County Chairman (in Texas). We put on the Republican primary election adhering to our state laws. Every voter in the Primary Election voted for their choice for president. The candidate for president is the person who won the most votes in Texas. The Republican State Chairman has no say in who is elected for candidate for president.
I don't believe California has a state law the Republican State Chairman can select the candidate for president he/she wants. If that were true, there is no reason to have a primary election for candidate for president.
Even if California had such a law (I don't believe that), it would have no bearing on other states election laws regarding holding a primary election choosing the presidential candidate.
