Blogging is light because of work obligations, but here is a good article by matt Tully entitled Conflicts of interest rampant at Indiana Statehouse.
I’ll just comment that it’s a tough balance between avoiding conflicts and the appearance of impropriety on one hand and putting legislators in a position to legislate in areas where they have expertise. Having a banker oversee the banking industry makes people understandably uneasy. But, for example, I can see if I were in the General Assembly where I’d have a lot to say and contribute to regulating the judiciary and the legal profession; and I think I’d do a decent job. (And I can see where I’d need a lot of education on banking before I’d be much good at regulating the banking industry.)
