Doctors, however, do not seem to be as liberal. I see more of a liberal trend occurring over several decades, in part a result of the general educational elite moving towards the democrats. However, doctors are more conservative than scientists probably because they operate in a more corporate setting; there is less public sector influence.
Doctors aren't as liberal as lawyers or academics, but they are far less Republican than they were 40 years ago.
But physicians are, on the whole, terrible with money. Most of them will never take an accounting or management course in their lives. That's why they tend to let the billing service they outsource their accounts to do the worrying about the money. My father has had years of post-doctoral training from some of the top teaching hospitals in the country. But if I try to go over his retirement accounts with him, basic math and financial terminology go completely over his head. If I ask him what medical procedures have the highest profit margins for him or what patient demographic generates the most revenue for his practice, he can't tell me. And most doctors can't. It's part of the reason they're such easy marks for pharmaceutical reps and people selling medical equipment.
I attribute that to the reason that most physicians, when they opt for public office, tend to be truly awful legislators and administrators.
