Is duke university predominantly democrat or republican?

I'm taking into account that there are only two schools of thought, Democrats and Republicans, which seems to be the case with many Americans nowadays. Most United States universities, professors and students are by predominately "Democrats" even in "Republican" strongholds like Oklahoma and Utah. You'll find more, maybe not a majority but more, "Republican" professors and students in business and economics departments or in the military universities (Air Force Academy, US Military Academy). Nothing is different at Duke where there tends to be more "Democrats" than "Republicans."
