Tech workers in SV seem to hate Trump, but tech workers are not only in SV. There are also tech workers at defense contractors all across the deep south, and they definitely do not hate Trump. They might roll their eyes at his antics or prefer a tougher stance on Russia, but "lock her up" is a very real desire. The H1B issue kind of resonates with them, since many are older people with families, though obviously the competition with H1Bs is indirect due to citizenship requirements at defense contractors.
