There are many Republicans and Democrats here in Silicon Valley. Recently Google as been hosting Presidential candidates from the Democratic side, I don't know what their plans are with the Republican candidates.
As I was reading about recent candidate visits, such as Giuliani in Burlingame, it occurred to me that there have been at most a handful of public events in Silicon Valley in which Bush or Cheney were the "guests of honor." I contrast this with the Clinton/Gore time, when both men seemed to be here pretty regularly, for both public and private get togethers. And I don't think it was just because Chelsea was at Stanford.
My perception is that both Bush and Cheney have a distaste for California, but this goes to another level around why the world epicenter of innovation and technology has not been on these guys' radar screen? Lots of money in these parts, in addition to ideas and businesses that are increasingly an important part of the US and global economy. Blind spot?
