I think the insurance industry will be much more Republican than a lot of other posters. What reason would a health insurance salesman have to vote Democratic when half of that party literally wants to abolish their job? Finance will also probably be more Republican, especially those not based in NYC.
I don't know about Sales in particular, but the ACA was generally supported by the health insurance industry and great for health insurance stock prices.
Even if we have Medicare for All, there will still likely be health insurance in some capacity, whether it's Medicare Advantage directly, or supplemental products to help cover copays/deductibles or non-covered services like Dental. We'd have to go well beyond what Canada has to not have any of that.
