Software Engineers: 79 Democrats for every 21 Republicans. Similar story for engineering overall (The most "conservative" engineering profession being chemical engineering)
You could argue the fact that the profession is predominantly male might mitigate some of this but the problem there is that the gender gap closes once you look at genders on a college-education basis: https://www.pewresearch.org/fact-tank/2018/11/08/the-2018-mi...
What I'm trying to say is that if we assume political affiliation does not correlate with skill (it doesn't AFAIK), and you hire based on merit, and you hire nation-wide, your software development team will skew left. And if your hiring focuses on major urban hubs it will skew even more left.
If you want to introduce artificial "balance" you are going to have to do affirmative action for political beliefs. This is challenging, as it's trivial for any individual to lie / reinvent themselves as a desirable political hire. If I wanted a job bad enough, and I knew they preferred hiring a certain political persuasion, I absolutely would pretend to be whatever they wanted me to be.
Initially and used to. Now, SV absolutely and without question is left leaning overall. To not see it means you’ve never been anywhere near or that you personally are so far left they look center or right ;)
That's a surprising conclusion... I always thought they skewed libertarian.
