She's probably aware of that, having lived here for 35 years, but experiencing it is a lot different than doing it. The other parties might show up on the presidential slate, but if there is no local party, they can't have local candidates.
In my party, the delegates were voted for at the conventions, the precinct, county and state. At precinct, I just asked for my name to be put down since I would be delivering ballots to the courthouse. At the county convention, we had to interview and present resumes, although we all know each other. Then we were recommended by the committee and voted on. There is a procedure as to which number you are. The first delegate is the highest elected official in the county. They rank the rest of us behind that person, and then rank the alternates. At state, the people who wanted to be delegates to national ran a campaign to be elected. I couldn't afford national; I could barely afford state, and that was sharing gas and a room, and eating what I brought. At state, we had general assembly, and caucused as a senatorial district and a congressional district, under different sets of rules. It was all very interesting. Hobnobbing helps us gain knowledge.
Even working only in the local elections is an eye opener. Did you know that the county election officials have to draw names of the candidates for each race to see who gets to be listed first and who next, and so on? Research has shown that if a voter doesn't know the candidates, the first on the ballot gets more votes, or if the person has a famous name, they will get more votes. I guess voters don't want to vote for a "nobody". When one of our children was about nine, they let him draw the names.
Once, I was on the committee to consider a voted ballot to see if the voter was actually voting legally. It was voted provisionally. I was once the election manager for my party, getting contracts for polling places and hiring all the election workers. It was interesting.
