I don't use social media much, but I do use Twitter mainly as PR and research for my small business (I'm freelance.) I'm always shocked how some of my contacts are very open about their political leanings, mainly through Twitter posts, seemingly unaware of how their clients or customers might not agree with their views (and damage their business.)
AIBU to think that if you are self-employed and reliant on certain core clients, you ought to be more careful about voicing strong political opinions? I say nothing about who I vote(d) for simply because I don't want to alienate clients I work with if they have different views.
