Occupations and voting

[Rockefeller GOP]

Just because the far left has discovered a hatred for law enforcement doesn't mean that's a GOP voting bloc.  Cops are government employees who don't make a whole lot, and I'd bet they vote Dem, especially in big cities.  They CERTAINLY vote to the left of business types.

Wall Street notoriously backs a tolerable and obvious winner (Obama '08, Clinton '96), but what's telling is their donations in an election where the outcome is uncertain.  In 2012, they gave Romney $356 million, compared to $170 million for an incumbent Obama.

How about among graduate/professional degree holders?

MD, DDS and MBA - mostly Republican

The rest would be majority Democrat - with several (PhD, MSW, MLS etc. being overwhelmingly so)

Republicans really don't lose the post-grad vote by THAT much, so given that those ones you mentioned are probably overwhelmingly Democratic, I'm guessing MBA is very Republican.
