I’ve never done this for the purpose you have, but my suggestion would be to do research into all your options. You’re able to see where they’ve worked, political donations, and other things might turn up that give you a clearer idea of where their political values lie.

There’s a couple of problems though. Board members have a fiduciary responsibility to the company to act in its best interests. Even if you get someone who is left leaning, they may not vote or conduct themselves in a way you’d prefer because of this.

Secondly, if you don’t already know these people, your voting block is probably too small to really influence the election. More shares is more voting power.
