intelligent mainstream economic commentators?

[David Dorkin]

I was wondering if anyone could give insight into the mindset of
relatively intelligent mainstream or liberal political and
economic commentators; are Kuttner and Reich, for example, aware of and
sympathetic to heterodox work?

Same questions regarding any others you can think of. Whom would PEN
listers consider to be interesting mainstream people who may be more
progressive or insightful than most working in journalism, business and
public affairs (not in overtly progressive of heterodox groups like URPE
etc) or even closet radicals. 

Thanks
