I haven’t downvoted anyone in this particular thread at least.

And I didn't mean to imply that the Treasurer is responsible for the state’s budget, just that he should have a strong understanding of it and be able to oversee spending. Lathrop’s site also says he has experience helping to manage the South Kingston school trust, and investment management of public funds is one role that the state Treasurer is responsible for. While I agree business experience isn’t a necessity, but my guess is that most state Treasurers have a fair amount.
