Is Mark Zuckerberg a Democrat or a Republican?

The answer previous to mine that stated that Mark Zuckerberg is a republican is factually inaccurate, Mark Zuckerberg has stated himself that he is neither a republican or democrat, however he is from a Jewish family and is an atheist, both tend to lean to the left. He also graduated from Phillips-Exeter Academy, the finest high school in the country, and the same as two of Americans greatest Authors John Irving and Gore Vidal (both very liberal). He in addition attended Harvard (extremely liberal) and is seemingly anti-censorship, and very charitable. Through reasonable assumption I would guess he would be very liberal and unfaithful to either political party.
