Maybe it's due to where you live, and the company you own.  I often felt the reverse was true, but I live in the semi-South and most of my life has been spent around military and vets, who lean fundamentalist (Especially among officers).  Then again every squadron has their "Squadron commie".

Tech supporters tend to be progressives.  Progressives tend to be liberal, and by definition dissatisfied (I don't think it's possible for a progressive to ever be satisfied, there's always more to fix)  It takes a lot to get people fired up for progressivism like OWS or anti-SOPA stuff.  (anti-SOPA is one of the few areas where progressives and conservatives can meet)

Michigan city+ tech company= very few conservatives.

I do think that natural state is one of the issues the left has- it's easier to accept the status quo then it is to always be fighting it- you get tired of it eventually.  This is why I think older people tend to skew reactionary- that and progressive belief becomes less in your self-interest as you get older and wealthier.
