I'll put this argument to bed for you

The University of Michigan has been performing detailed election demographic studies since 1948.
for all you slow learners out there, all their election data is tabular, so you have to pull the data into a database and query individual categories for results.
I'll summarize for you, but look at the data and verify it for yourself.
This data tells us that indeed, the majority of individuals with college degrees do vote democrat, HOWEVER, those with POST graduate degrees lean slightly republican
It also tells us that the overwhelming majority of blacks and latinos vote democrat, no surprise there

That depends upon the individual

I've had a long career as a computer programmer and never taken a programming language class. I have a BSCS and a masters but placed out of the language classes just by study on my own.
Through the years I've learned that some people have an affinity for computer programming and learn it quickly, while others can't seem to program even after post-graduate studies. A friend of mine got his degrees with "the help of study groups," meaning that he copied all his programs off of others. Not surprisingly he hasn't been able to hold any coding job for long. He has a masters in database design but can only get SQA jobs

Republicans have 4 year degress

Republicans are significantly more likely than Democrats to have 4-year college degrees. The trends for the years 1955 through 2004 are shown by gender in the graphs below, reproduced with permission from Democrats and Republicans — Rhetoric and Reality, a book published in 2008 by Joseph Fried.[62] These graphs depict results obtained by Fried from the National Election Studies (NES) database.

Regarding graduate-level degrees (masters or doctorate), there is a rough parity between Democrats and Republicans

Actually, you should research that statement
