What's important for you to know is that Trump / Kennedy will run unopposed in the next special election within the coming weeks.
Will we have a special election ? That would be great but we would need to do way too much cleanup beforehand that seems to be longer than weeks? Maybe President Trump might just appoint him VP in the interim and then an election can take place afterwards ? just speculating . But I do believe that the names Trump/Kennedy will be seen everywhere when the time comes :)
