OpenSecrets.org is there for your disposal. Use it! Think about businesses you use regularly, products you buy, artists you watch or support. Chances are likely they have a profile on OpenSecrets and you can see who they support. I for one am planning to move my brokerage out of Schwab who donated overwhelming to Republican campaigns and maybe move my insurance to Progressive (not just because of the name, their employees donate significantly more to Democrats).
The weight of billionaires is behind Trump but at the end of the day money will drive his decisions. Taking money away from his donors takes money away from him.
See my reply below. Got confused but I’ll leave this here anyway.
There’s probably no big bank that doesn’t donate to Republicans at all but some do lean to the left. Here’s a summary page: https://www.opensecrets.org/industries/indus?cycle=2024&ind=F03
Overall you’re probably best sticking to a credit union that doesn’t donate politically at all (as an organization) but in my experience they’re a noticeable downgrade in quality.
Sorry, I was thinking of banks not investing. Couldn’t find a ranking but Vanguard seems to lean Democratic.
Edit: Damn. Digging deeper it looks like most trading companies are fucking cesspools.
Edit: Another point for Vanguard: the current CEO has a history of contributing to Democrats.
