I worked one day a week in an office in San Jose and a guy wore his MAGA hat to work the day after Trump won in 2016, he got about 25% of the vote in Santa Clara county so plenty of them here. There are also a few Trump emblazoned trucks/houses if you happen to spend much time in rural areas outside of San Jose/San Francisco. Also, my local little town newspaper had a front page story about a couple that were GOP supporters that went to the Trump inauguration.
