If Trump gets as much as 35% of Santa Clara County's vote it will gast my flabber. There have been Silicon Valley execs boosting Dem Presidential candidates at least since the execs of Tandem Computers and Silicon Graphics hosted speeches at their companies for Bill Clinton in 1992. Both companies are long defunct, so don't worry if you've never heard of them. Tandem (not Tandy Corporation, owner of Radio Shack) was my employer at the time, so I was less than thrilled (attendance was voluntary, of course).
