I would have political uniformity which would prevent Red vs Blue infighting.
#Warning# This isn't an attempt at flamebait, it's something like a hypothesis.
I would also likely be able to hire from a undervalued portion of Silicon Valley, I suspect I'd be able to get talented Eastern European, Asian and white men at discount rates. They wouldn't have to deal with PC from HR and other firms may be less willing to hire them.
It is not unusual for a sector of the economy to have a political slant. Everybody knows health/care is mostly leftist, military/intelligence is mostly rightist. These are slight tilts but the net affect has an enormous sway over sector thinking/dogma. I suspect SV will split along such lines (right companies, left companies).
