Just for information, I heard about the time there was a problem with someone being Speaker and Lieutenant Governor. After that time there was an amendment (Improving the chain of command amendment) accepted by the population in July 2013.

Not sure if it was modified after it was adopted. It doesn't specify who runs the booth for speaker nomination.
