Have you ever watched a CSB political speech? As he’s standing on the stage making his speeches, there’s tacky “dramatic” music playing in the background. It’s not dubbed on during the TV broadcast; it’s actually playing on site.
Like kissing babies and hugging children, it works. It elevates the speaker and keeps the observers focused on the event. Like waving flags in America. “Hey! Apathetic masses! I’m here!”
People who’ve been working all day and go to a rally need more than a speech. Now, why his campaign choses that type of music is what you really want to know. I’d say it is just a matter of preference/consensus?
