Mostly agree but I think that personal trainers will vote for Trump, delivery may vote for Biden, clergy and logging may vote for him too. I feel like a lot of this is just based off of stereotypes I have about what kinds of people do these professions. Generally, I think Biden will do better among careers that require higher education or are more in the creative field, wheras Trump will do better among people who do things that are more physical for their job.
