Silicon Valley has a reputation for leaning left.
Facebook COO Sheryl Sandberg and Google exec Marissa Mayer have hosted big fundraisers for Democratic candidates.
Ex-Google CEO Eric Schmidt is a huge Obama booster.
Steve Jobs offered to help make commercials for Obama's 2012 campaign.
But the truth is that there is also a very strong libertarian strain in the Valley.
Sometimes libertarian-leaning Silicon Valley titans even almost allow themselves to be called Republicans.
Take Marc Andreessen, for example.
He has contributed $100,000 to Republican presidential candidate Mitt Romney's campaign via a SuperPAC.
Andreessen is the biggest fish there is in Valley right now. He's on the board of Facebook and HP. He's already a huge investor in startups through his VC firm, Andreessen Horowitz, and he still has billions more to seed.
In this CNBC clip, Andreessen says he supports Romney because he is a "dyed-in-the-wool" businessman who understand that "regulations" get in the way of business.
Andreessen says he used to support Democrats – like Clinton/Gore, for example – but "I turned 40 last year and so I figured it was time to make the switch."
It should be said that Andreessen disagrees with Romney's views on China.
